While its true that Gildarts is stronger than Bluenote, its also true that Blunote was actually able to fight him for a while when Gildarts was acting serious, while Natsu sees Gildarts act serious and he cries like a Zeref (no offense to Zeref since he is my favorite)! You can't say he got one punched since they had a long fight that resulted in a "Gildarts Punch"(spell/technique that has a long name). Though I believe that Zero and Bluenote would be nearly equal, I'd say Bluenote has an edge on Zero with the gravity magic and Blackhole spell.

In the end I guess its tough to say who is the better, since Bluenote's magic is more cheap than powerful, so maybe I'd have to give it to Zero. IDK really, and I feel that no matter what I'll get some fan hate from this whether I sided with Bluenote or Zero, but we can all agree that Gildarts can make them both his b*tch.
