First off all Naruto and Avatar can not match the ridicoulously oversized plot that is One Piece. Basically one piece is a bit more on the fast side like avatar and FMA. The moves don't really need to be explained.
As for Naruto Its plot is pretty simple and its action drags on. Thats why I highly reccomend the Sasuke retrieval arc ( Best Anime Arc IMO) The action was much more fast paced then the rest off the series and since the animation for Naruto only gets better The grass country arc will be so badass.
Avatar moves fast in fights and never pauses and I don't care whether they show blood or not. Avatar has had a very short time to develope though so it should be interesting. All I hope is That It ends when it needs to end, when they beat Ozai. Naruto should end when they finish off Akatsuki and Who the Hell knows when one piece will end Its not like there is this mysterious big boss like Ozai orAkatsuki leader to oppose them mostly just a bunch of mini-bosses.
Let me just say how the @#$%! could you not include @#$%ing Bleach.
Well I hope somebody actually reads this.
