I'm more into comics it gets annoying as hell tho trying to get all they tie ins for a certain arc, with certain events (e.g. A vs. X, Fear itself) I'm more of a Marvel fan DC has its moments but to each their own. Been following Naruto from day one tho anime watched most of the fillers... the last round was kinda bunk tho. I'll do a quick break down of my pros and cons of both Manga and Comics
Manga-
Pros:Weekly Releases, Variety (pretty sure theres a manga out there about everything/ variety in themes) Well developed main characters
Cons: Black and white print, story gets lost and meaning gets lost in translation, hard to find hard copies of your favorite series, locally , story can be stagnant , and plots can be repetitive
Comics: Pros : 90% of characters are well developed and have some sort of pertinent history, color print, easier accessed locally to hard copies
Cons: tie ins , released at a slower, story lines / plots are basically the same, multiverse concept (gets to be a pain in the ass)
Despite all the cons of comics is my choice. @ the op make a actual poll its not that difficult.
