You can't really say they chose the better option because Vegeta never provided them the options. Only Goku. The only character who possibly heard the other option is Kaio. Because the Rou Kaioshin and the Kibitokai were wondering why he wanted to speak to everyone so they obviously didn't hear everything they said. But Kai is probably going to prefer the Genki Dama as the finisher because it's his pride and joy of techniques. He even says to Vegeta that he loves that it's going to be the closer of the fight.
dragonballer wrote:i very sure they would bring gohan and gotenks to fight buu if the genki-dama failed. that ridiculous history would be like this: buu was flying at the space destroying planets after he blow up kaiohshinkai.buu sensed a powerful ki and looked back,but before he could even look his enemy he was already destroyed."good bye,universe destroyer" said gohan in a space suit with kibitoshin.
Well, the problem is that you don't know what Pure Boo would do after the Genki Dama failed. He could leave Earth as the very last thing to be destroyed. Kibitokai wouldn't have the power to get Gohan there until a little rest. Pure Boo may just show up at Namek and blow Namek up before Kibitokai can do anything. So many things could go wrong.
dragonballer wrote:except that goku said it will be alright because he will train and win the fight if the evil/pure buu appears again.that means they would have a chance to fight, if gohan can blow the old and new buu in 1 second,i don't think even buu could destroy earth.in fact, kid buu managed to explode the planet in dragon ball xenoverse,kid buu only succeded because that buu strangely was able to put up a good fight with gohan and not destroyed with one punch.
Goku did say that. But Goku has the Shunkan Idou. So it would be all right if he is strong enough to take on Boo. For Gohan and Gotenks they would still have to fly around the world and by that time it may be too late. It's even worse for Gotenks because two characters have to meet up and do a dance to fuse. Wasting a lot of time. Like if it takes Gohan 30 seconds to get to the other side of Earth then the new Boo would have plenty of time to blow up Earth.

.
Gohan and Gotenks were only caught off-guard because that Boo was smart though. This one isn't. How do we know he isn't going to instinctively try and throw the stuff at them? They would be much too strong to get caught in that type of absorption. If this Boo wasn't so animal-like then I would understand. This Boo lacks the brains to catch these characters off-guard in this manner.
Confidence Matters wrote:False. Goku was 100% when he first transformed and attacked Kid Boo. He stated so, and he even opened up with the Kamehameha, which BASED SOLELY ON GOKU"S STATEMENT ABOUT GOING ALL OUT (100%) FOR THE SAKE OF THE UNIVERSE, was at full power. These 2 concrete facts simply outweigh Goku's ONE statement. Hell, on the VizBig edition of the manga, he said he had been tryin' to finish Kid Boo.
Incorrect. How do you know Goku was at 100% when he first transformed? Goku may have said he would go all out. That could mean in transformations only. Or, Goku transformed and wasn't at maximum power at the start of the fight. Trying to build his way up to that battle power over the course of the fight but failing. And don't speak half the conversation making it sound like Goku was trying to finish Pure Boo at 100% already because if you add the dialogue Vegeta said before that then it is clear that he needed to build up his Ki. What Goku said was he had been tryin' to build up his Ki to finish Pure Boo. But hasn't been able to. That is what is said. I'll even quote straight from the Viz translation:
Viz wrote:Vegeta: "Don't mind me. Finish him off! Build up your Ki with SSJ3 and you should be able to obliterate him!"
Goku: Well... I've been tryin' to, but... I haven't had the chance!"
I'm sorry. But it's a simple fact that if Goku was at 100% and launched the Kamehameha he wouldn't be spouting that he needed his full power to defeat Pure Boo. Never in the history of dragon ball has a character used his full power and still believed their full power is enough to beat someone. Look at the most arrogant character in the series, Vegeta. He believed he could beat Freeza's final form and launched all of his power at Freeza. Only for Freeza to dispatch it. Causing him to come to the realisation that he couldn't beat him.
Confidence Matters wrote:He overestimated himself because he himself said he thought he could do better, and because he said himself he needed a whole minute to generate enough ki to finish off Boo. Notice Goku doesn't say "I need a minute to get to full power" - he said "I need a minute to gather enough ki to wipe him off"
He didn't say he thought he could do better. What he said was "But I thought this would be better..." as in he thought it would be better to fight without the Potara. Goku also says later "I got close to full power... ...But I'm losing Ki again...!" So clearly he is aiming for full power.
Confidence Matters wrote:That is a clear indication that he was going to gather energy like a special beam cannon-like attack, which would have been beyond his power level like Piccolo did in the Saiyan Saga.
Charging Ki attacks and charging Ki are two different things. In the Saiyan Saga Piccolo, who was already at 100% of his full power, charged an attack that amplified his full power Ki. Vegeta does it against Cell, charging his Final Flash to levels that would damage Cell. Goku also did it against Cell when he was charging his Kamehameha. Even if you believe he was at 100% at the start, did he charge the Kamehameha? No. He didn't even say its name. He just did the hand gestures. So you could also look at the scenario as Goku needed a gap to produce a properly charged Kamehameha but Boo didn't allow him by attacking quickly.
