By Personal opinions? Then everyone is right.
By popular vote on VGchartz, I'd guess KZ2.
Critically, right now according to Metacritic and Gamerankings it goes Halo 3, Gears 2, Killzone 2.
Sales also goes Halo 3, Gears 2, Killzone.
Any other way to look at it? Not sure. I love Halo, but play Gears 2 more often (and don't have a PS3) so likely my opinion is just as biased as many others on this site will (and have) been.
