I dislike Neogaf because of the crappy layout (it's simple but also very cheap looking) and the hivemind mentality. I don't feel like there's much open discussion about controversial things and that it's just a bunch of people agreeing with one another or chastising the one person who dared to speak differently.
To add: the mods do ban on personal opinion, bias, and favoritism. I've never been banned and my acount is 7 years old. I've used neogaf to find people to play random games with or discuss anime. I've generally stopped doing both because none of them were nice experiences.
