I am a big anime fan, I watched dbz/one piece/naruto/bleach although only a bit of One Piece, DBZ was years ago, been waiting for more Naruto and Bleach's recent season has been a bit of a drag. Really my favourite of long running Shounen (the genre of the shows you mentioned) is Fairy Tail which is a heap of fun, Fairy Tail breaks up the action with comedy, they manage to make it pretty serious and feel for the characters, but also have fun, plus characters actually change clothes. Erza also rocks, I am a big fanboy about her, and she is a good example of a strong female character when there are usually not many.
My favourite genre really is comedy, of which some of my favourite shows are Azumanga Daioh, Shinryaku! Ika Musume, Hayate the Combat Butler, Seitokai no Ichizon and Kanon. My current avatar at the moment is from Baka to Test to Shoukanjuu which is also a very funny show, which I am awaiting for a release or and a second season.
My favourite show I am watching at the moment might be Kore wa Zombie Desu ka, which really kind of fun and interesting, a strange mix between comedy and drama that works quite well. Last season's favourite was Shinryaku! Ika Musume, which despite being very clean was one of the funiest things I had seen in a long time, the shows description sounds pretty bad, but it is actually really good.
Fairy Tail FTW.
