You know, using feats isn't really a great idea to prove superiority in FTverse.

Consider the recent Natsu vs. Bluenote fight. 8 years ago, Bluenote was a bit below Gildarts. His personality is such that he'd train a lot to become stronger. Even then, let's hold him back and say that he's just equal to Gildarts ater 8 years, even though he has a 7 years advantage over the latter. Then Natsu one-shots him. So Natsu is stronger than Gildarts, right?

The basic flaw with the above theory is that, even with the 7 year advantage and his power-hungry personality, there would actually be a huge power gap between Gildarts and Bluenote in the former's favour. Because this is shonen. Power scaling is always awry. And, although he's one of my fav mangaka, Mashima definitely is not great at power scaling.

TL;DR: Feats are too inconsistent in FTverse to use in discussions. You'd be better off if you gave the vast power difference speech that Aizen gave Soi Fon (not gonna use the other name >.>) to prove Laxus' superiority over Minerva. :P
