Gamer's Hell is pretty sucky in comparison, the saving grace is that it's free.
Filefront is great (not compatible with DLM's though)
FanGaming is great (www.fangaming.com) free, lots of ads, but it's REALLY fast.
GameDaily is also great, free, also REALLY fast, though sometimes too fast for downloads.
Fileplanet is junk, I simply hate them so that's an opinion, try it yourself - wait times and their spyware + crappy as hell Gamespy service.
