4chan sucks, never got my attention.
7chan however aside from /b/ which I don't go on, It's really REALLY less handicapped, at 7chan it has more diverse boards such as
/z/ zombies, for the paranoid people who think a zombie apocalypse is going to happen
/x/ paranoid, for the paranoid people.
/hi/ history, for conversations about history. (Very good board)
/rx/ drugs, for stoners.
/w/ weapons, 4chan also has a weapons board but this one is way less handicapped.
