1) FT arc SSB Goku (1st appearence, the one that fought next to SS Trunks) vs U6 arc SSBKK Goku (regular kaioken)
(if FT arc Goku wins, U6 arc version goes KKx10, and SS Trunks aids his contemporary ally)
SSBKK Goku wins. Goku never got particularly stronger in the FT arc and not much time passed at all. Goku didn't even manage to master the KK + SSB combo.
2) FT arc SSB Goku (the one that learned Black killed Goten and Chichi) vs U6 arc Hit
(Time Skip at full power, the one that SSBKKx10 was struggling to keep up with before giving up)
Goku absolutely had more time to acclimate to Hit's time skip. As we saw in their rematch, the time skip itself was something Goku could handle in Blue. Hence, it could go either way, but I would give Hit the advantage here because of how he was able to still fight Goku in KKx10.
3) SSR Trunks vs U6 arc SSBKKx10 Goku
(It's the non-spirit bomb version of Trunks, the one that with his father couldn't respond to Halo Zamasu's big attack or the one that jumped to fight MZ after Vegito defused. The former one is "brand new", the latter has already taken damage)
SSBKKx10 Goku easily. Rage Trunks was very much portrayed as on par with the Blues, and sometimes even weaker. Still, he used
a lot of power to knock Black away, but then the latter came back apparently no worse for wear, so he must be somewhat weaker than other characters at that level. In other words, a Super Saiyan Blue multiplying his power tenfolds would be too much for him.
4) Moro arc SSG Goku(the one that fought Saganbo) vs Ikari Broly
(a post-movie version of the guy, zenkai'd and all)
Wait, SSG Goku fought Saganbo? Still Broly, tho. SSG Goku cannot suddenly reached the same level of power as Goku's previous SSB in less than a year of regular training.
5) Moro arc SSB Goku that beat up Saganbo vs SS Broly (post-movie Broly or movie Broly, if both even better)
Broly both times. SS Broly is a monster, but Goku would
definitely hold his own much better than before.
6) Powerhouse Saganbo vs Black Rose
(Saganbo before Moro got carried away. Strongest Black we know. Can't zenkai on the spot, he can summon the scythe but no weird clones or stuff like that)
Sadly, I would say it could go either way. That Saganbo was trashing the same Gohan that tied with Kefla, who should at the very least be a SSB-level character in the manga (having Kale's raw power that wiped the floor with Freeza and almost clocked SSB Goku's face), while Black at least could be a little stronger than that since both Freeza and Vegeta said they could handle Kale, and he should be on their level at least.
7) ToP SSG Goku vs BoG Beerus
(Goku knows he might have a chance from the start, Beerus is confident but goes full power from that time, is that enough? he can only access his real retconned full power if he flies off the planet safely, can he escape Goku?)
Assuming that the Goku that fought Beerus in the movie is at the same strenght of the one in the series, than I can see Movie!Beerus actually having to fight at full power to win.
8 ) SS4 Gotenks vs Buuhan.
(In the ROSAT they grew a tail, they saw the moon or something, leave the ROSAT after Buu absorbed Gohan and they fuse and go SS4. Gotenks knows about the time limit. Buuhan does not)
Probably SSj4 Gotenks. Ultimate Gohan was maybe a little stronger than SSj3 Gotenks, who was more or less on par to stronger than Super Buu. So by absorbing Gohan, Super Buu more or less doubled his power. SSj4 is confirmed as, what again, a 10x multiplier over SSj3? More than enough to dominate Buu like Super Vegito did.
9) Super 17 vs Ih Shenron
(The Super 17 that absorbed everything SS4 Goku sent his away, and that absorbed so much from 18 right before Goku killed him. The one-star dragon that trashed SS4 Goku, no dragons absorbed. He knows the android absorbs ki)
The way I saw the show, and disregarding GT's
atrocious scaling continuity, it could be a very even fight, with the dragon having the advantage in raw power.
10) GT Uub (that lost to Vegeta Baby) vs ToP SS2 Caulifla
(Uub can fuse with Mr. Buu if this go bad. Caulifla can get Kyabbe, not Kale, to help her)
Hmmm, I would say it could be somewhat evenly matched at first, since Uub is supposed to be as strong as Pure/Kid Buu after training for so long with Goku, while Caulifla is an unusually powerful SSj2. As Majuub, I can actually see him dominating both Caulifla and Cabba. I'd say Berserk Kale would be required to beat Majuub.
11) GT SS4 Goku that fought Omega Shenron is recruited for the ToP. Who can he take? who takes him? (the nakama-healed Goku but with his sight back)
You mean Super Full Power Saiyan 4? He would at the very least be a top tier contestant in the ToP. Perhaps not to the level of the Blues, Jiren, Kefla, etc. But he could very well wipe the weaker opponents and, perhaps, hold his own against Kale's Berserk state or even her SSj2.
12) Who can defeat SS4 Goku from the Baby arc in the ToP? (his FP form that defeated the ape)
Super Full Power Saiyan 4 Goku (jeez that's a mouthfull) from the Baby saga? Believe it or not, he shouldn't be
much weaker than his Shadow Dragon arc self, since Goku didn't really train or fought
really strong opponents between those arcs (except Super 17, but only him, and he never trained to increase his power against him). So, I would keep the same statement as above. I would say Hit could put him down, as could everyone on his level and above (Dyspo with his super speed included, at least until Goku figures him out).
13) Who can defeat SS4 Goku that left with Shenron in the ToP? (no weird dragon powers)
I have no idea. It's impossible to say if he got any stronger at all and by how much, so it's meaningless.
