Maybe, I still don't know what i want. DX
But prepare yourself, cuz the theme would have to be uber cutesy, like lil' mini hearts and pastels and soft colors and junk. xD
Haha, like I said I'm not entirely too sure about what i love about all three. o3o" But yes, One Piece's story is very deep, especially with the historic factor woven into it and junk. Bleach is pretty much just full on action, and Fairy Tail is more of the "fun" animes, which is a nice refreshing taste from so many that are so dramatic and serious.
As for favorite arc...hmm. I'd have to say the current one with the Games. Edolas was probably my least favorite, but I think Mystogan was one of my favorite mages when he was still in Earthland. I mean, he had no magic naturally, had to use staves he took from his land, and he STILL fought toe-to-toe with Laxus. How BAMF can you GET?
