Most of this will be re-wording from youtube comments i wrote explaining the omniverse tournament to other people along with some predictions. it mainly started when i was asked if the upcoming omniverse tournament will really be a big deal since they felt that the universe 6 vs universe 7 tournament was disappointing.
Let's start from the beginning. dragon ball super started off with questionable fighting animations. it was overall decent, but did not live up to the series hype at all. over time as we've seen more major battles, we can see that the animations have been getting better and better. i'll admit, even the battle between vegito and zamasu could have been better, but it was still a huge improvement over many dbs battles before it. if you go over all of the past dbs battles you can see that the characters in each battle are having their capabilities utilized and emphasized carefully. we had piccolo extending his arm from the first time since dragon ball (i think). we've seen frost use unique methods to beat even goku (we've never seen goku beat that way before). we've even seen hit in action (who is a new type of fighter with unique talents). not to mention two other fighters in universe 6 during the universe 6 vs universe 7 tournament. the emphasis on the utilization of character capabilities was most prominent during goku vs goku black, when we were pretty much watching goku fight himself yet both had completely different fighting styles. there are obviously other battles that emphasize this, but you get my point. it's a matter of variety which is making battles unique.
DBS started off a bit rocky, but when you look past that you will see the genius. this is more emphasized for the omniverse tournament. i shall explain...
___________________________________
The main differences between the universe 7 vs universe 6 tournament and the upcoming omniverse tournament are the origins, the stakes, and the hype. this tournament was born from the universe 7 vs universe 6 tournament by the omni king himself out of an earnest desire to see this happen. now there are TWO omni kings that will be personally overseeing this tournament. all of the angels, gods of destruction, and kai are duty bound to do whatever it takes to make sure they please/impress the omni king (and they don't want to be erased). that alone is a massive difference from the origins of the universe 7 vs universe 6 tournament which champa originally proposed because he was a little bit hungry.
Apparently whichever universe loses in the omniverse tournament will be erased from existence. this is something that the gods of destruction and the kai fear greatly. obviously most or all of the participating fighters will be motivated by these stakes as well. it is also an extremely high possibility that there is a huge reward for the winning universe, and/or rewards directly promised to the fighters based on their performance by their god of destruction or kai. these stakes are many times greater than the stakes that were present during the universe 7 vs universe 6 tournament.
Now, if you go back to dragon ball and watch some tournament battles like yamcha vs tien. that battle was awesome because they had unique fighting styles and they were giving it their all. it had nothing to do with having insane, immeasurable power levels or transformations. with that in mind consider this; each universe has 10 fighters to partake in the omniverse tournament on behalf of their universe's survival. this opens up insane potential for up to 110 unique and powerful fighters that we know little to nothing of.
___________________________________
Already in universe 7 we have 10 confirmed fighters. we can ignore goku and vegeta (i will explain later). we have buu (who did not participate in the universe 7 vs universe 6 tournament and has massive potential. don't forget he was once an unbeatable enemy with many insane unique traits), we have three powerful humans (each unique. one with no nose, one with three eyes, and one with an insane number of years in experience), we have two androids (again they used to be unbeatable enemies with many insane unique traits including that they can't be sensed), we have gohan (half breed with insane potential. keep in mind that gohan's power only truly shined when he was needed. with stakes as high as this tournament, he is needed), and we have a once reincarnated twice merged namek (for me personally it has always been a treat to see piccolo engage in battle (especially in dbs). his character and style are extremely unique, not to mention he is a master tactician and strategist).
That alone is just what we know. when you consider the potential uniqueness for the other 110 fighters that will be participating in the omniverse tournament, the hype is limitless. obviously a lot of the hype is also about seeing the other angels, gods of destruction and kai. they are most likely not going to battle in the tournament, but they still have an insane influence on how things will play out. it is very important to note that a gathering of all the universes like this is probably an extreme rarity. this is most likely the first omniverse tournament to ever happen from their perspective.
EDIT: the angels, gods of destruction, and kai. their presence alone will be so much more important than most people think. it's reasonable to think that not all of the gods of destruction are on good terms with each other. they are used to being the most destructive force in their universe and in control, yet they have the power to challenge each other. simply by killing their kai, the gods of destruction can safely kill each other and probably deactivate their angel. the omni king might not care too much if this is done. maybe he will simply erase that entire universe if their kai and god of destruction happens to be eliminated. this can be a way of efficiently thinning out competition.
You have to understand that this is the end game. tournaments have always been the center of hype in the dragon ball franchise. after goku beat piccolo in dragon ball, there has never been a proper and complete tournament since then. this is because there simply hasn't been anyone in universe 7 that can make it interesting enough for goku and vegeta during a tournament. so the writer had to turn things upside down and add in side stories during tournaments. this problem is solved for two reasons. the first reason being that this tournament will bring together the strongest from ALL of the universes (i will explain the second reason soon).
Another problem with DBS is that it simply did not have intensity at least on the same level as DBZ. obviously the two shows are different, but they are the same as well. the reasons the show was lacking in intensity from the beginning are: first of all, the first two seasons was pretty much a repeat of the battle of gods and revival of f movies which we already knew the endings to. second, because every time an enemy shows up we have beerus and whis chilling on the side ready to catch rebound. this problem is solved because in this tournament, no one is safe and we have no idea what we're getting into.
It's not about goku vs vegeta anymore. it's also not about every other z fighter being completely useless compared to goku and vegeta. this is genius writing. we wanted to see goku and vegeta go all out in a struggle for survival. we also wanted to see vegito and trunks once more. in the zamasu arc it was key to remove goku and vegeta from the watch of beerus and whis to make the danger more prominent. that was just a way of taking care of unfinished business because goku and vegeta will be battling LAST in the tournament. we know that goku and vegeta always have a way of surprising us, but no one cares about seeing a new super saiyan transformation anymore. no one cares about seeing goku and vegeta getting stronger anymore.
Think about it. they have only stated that in the omniverse tournament, losing universes will be destroyed, but if it was that simple, wouldn't it be pointless to have 10 fighters per universe? i think it will be that each universe that loses 5 times will be erased. each universe that wins 5 times BEFORE losing 5 times will be exempted from excision. this will ensure that important universes will survive while still maintaining the thrill and intensity of possible nullification. also i think it might be pretty boring if only one universe gets to survive, because it will be completely obvious which universe that will be, and it will also be very lame to be introduced to unique universes knowing they will just get erased.
EDIT: or they could make it interesting and the rule can be something like "at least 5 fighters from each universe must win at least once to save their universe". this will completely prevent carrying by up to 4 fighters within a single universe. there's a chance the rule can also be "each universe needs to build up at least a total of 10 wins to save their universe". with this, there can be carriers but it is very risky relying on few fighters to carry.
Anyway, consider this. in universe 7 we have goku and vegeta. in universe 6 there is hit. these fighters are of a uniquely high caliber. this caliber of fighter is NOT in every universe as we've seen with universe 10. that is why the rule that each universe that loses 5 times first will be destroyed is crucial. this will allow a much higher intensity for battles that goku and vegeta are not taking part in because goku and vegeta will be battling LAST. there may only be 2-10 fighters participating in the tournament that have the power to challenge goku and vegeta. the majority of the other fighters from other universes will be roughly as strong as android 18 maybe. it is the only thing that makes sense.
Imagine universe 7 has 4 losses and it is android 17's turn to battle against a member of another universe that we've grown attached to that also has 4 losses. how would you feel about such a battle knowing that it will decide everything?
Of course, the winning universe will survive and receive the honor to ask anything from the omni kings (who should be able to grant them anything they want, or maybe they will use the super dragon balls). i think goku will be the main attraction and ask for the other universes that were erased to be brought back. for some reason that feels like a major spoiler alert even though i have no clue what will happen myself.
Dragon ball multiverse is great, but with DBS we are having a divine tournament. completely unique characters and battles with the highest stakes. all cards are on the table.
