I find the Gear 4 design really shitty.
But I also think it matches the aesthetic from Oda's work.

About Bleach....I don't want to go too much into it, especially considering I dropped the series in the middle of the battle against the Espadas. I simply found it completely uninspired. I never really liked Kubo's drawings, his environments always looked extremely plain.
I only have good memories from the Soul Society arc. After that, I don't know. Meh.
Same with Naruto. I dropped it I don't even know when. pretty sure was at the beginning of Sasuke forming that little group of extras of his. Did it happen before or after Shikamaru fighting the immortal dude? Because I also remember that. Aside from it, meh. Dropped and have 0 interest in picking it back up.
It's not like I only care about these extremely complex plots or whatever, I love Saint Seya Lost Canvas, and Saint Seya is an extremely simple manga only about battles. :P
But those two....I don't know. They lost their "touch" for me.

My top favorite manga/anime would be something like
One Piece>>FMA Brotherhood>>Slam Dunk>>Death Note>>Hajime no Ippo.
But at least Naruto and Bleach hold a special place in my heart. They were my first and second Subbed Animes.
