NeoGAF is still more relevant as a site welcome for (sometimes) mature gamers. Never been on Reeeset and recently saw their page for the first time. I wanted to make sure I wasn't being biased by saying they were total trash...nope...they are beyond trash. There's virtual nothing gaming related over there. Seems like it's a mess of politics in every category. For the record, I don't care if someone is left or right wing (as I tend to stay out of politics and controversy); they modeled their templates directly on GAFs. However, everything is whiny left wing politics. I've also never seen bans fly up so fast. I mean, some people need to be banned...but many on there were simply looking to give honest non-biased/non-political contribution to gaming discussion. Something as seemingly harmless as 'Lara Croft is a cutie' will get you banned.
GAF is honestly hotter than many of the other sites, too. I see politics are respectfully kept in their category, consoles warring and trolling are discouraged (great moderation here and fair), and NeoGAF still maintains the human element (users with diverse personalities, care, and humor).
