Goku wins.
Why?
Well what was the strongest attack the space time barrier teleported. It was a TBB from the Nine Tails at 100%. Goku can dish out attacks much stronger then mountain/city busting. He can do planet busting as a SSJ3 and the attack fully powered up. To say the space time barrier can teleport attacks stronger then what is shown in the manga is something called a No Limit Fallacy. It means that you are saying it could teleport an attack much stronger then what is shown in the manga when there is no proof to say it can. It is stupid to try to argue it can or can't without the feats to back it up. It would be like saying Minato could absorb a blast that would destroy a planet/sun/solar system/galaxy/universe when all it has shown was to teleport an attack that might be stronger then mountain bursting(scaling to what BM Naruto has done with Kurama). You get what I'm saying right? Arguing he can do something which he has shown he can't is dumb.
Let's just say he can for argument sake. How many times do you think Minato could use the attack before he's out of chakra. During the flashback when he used the skill he did FGT a few times, FGTv2 once, a Rasengan, and that space time barrier once before he was worn out. In fact, using the space time barrier on such a strong attack wore him out very fast. How many Space time barriers do you think Minato has in him? 2? 3 maybe? I can guarantee you Goku has more Kamehameha waves then Minato can do that.
Not to mention all Minato can do is put up a good defense. All of his attacks would do nothing to someone as strong as Goku. The meme itself is stupid to use the logic it did. Minato can beat Goku with a defensive technique. Lol. Ya right.
