just finished naruto and ID(well caught up)

which one should i watch next?(which one is better?)

There is really no answer to this since it involves different perceptions, opinions, and preferences of the watcher. I suggest you look at some reviews, or the first couple pages of the discussion threads before making a topic like this. You have gotten a few opinions, that should be enough, please look into an anime more before making a topic like this. Thanks.
