Re: How on earth is Tobirama better than Minato?
Not that I disagree with your beliefs as a whole but . . .
Tobirama had to get cut in half so he could mark Juubito. Minato escaped his attack with losing only one arm, and from a Juubito with control of his attacks.
The man was Obito's first victim, and wasn't expecting Obito to have teleportation level speed. Minato has already witnessed Obito's speed thus could brace himself and prepare accordingly.
Then people are saying he could use FTG he kunai as well, then why the f*#k didn't he use it before he got killed by 20 nin, when Minato was known for taking out platoons in the blink of an eye using his FTG.
We have no idea who those twenty ninja were and we have no idea how much chakra Tobirama had wasted up to that point either. If those were twenty Kakashi-level, Darui-level, or Bee-level "Jonins" (which isn't really "Jonin" level), it would be understandable. Regardless, we have no idea what transpired other than Tobirama died against twenty ninja.
How on earth could Tobirama who freaking got fodderised by 20 nin be anywhere on par with this guy's reflexes?
And now you're talking as if you know what happened. What makes you think he was "fodderized" when you never saw the scenario transpire?
Tobirama refers to FTG as shunshin since he said so not only when they arrived the the battlefield, but also when Minato slashed Obito. That also implies that he admitted his FTG to be inferior to Minato's.
Or it could just be translation inconsistency. And FTG is FTG - its an instant technique, until shown otherwise. The only thing that Minato has shown superiority in is FTG application (i.e. using it with Kunais). Minato arrived on the battlefield via a kunai so it would make sense that Tobirama was complimenting Minato on superior application of FTG.
