Number of players means nothing--the first Gears' multiplayer beat the pants off the first Resistance, when it had 8 players to R1's 40.
I say Gears 2, because I like its' premise of intimate battles where every single team member's life is vital--in the main game mode, if you die, your 5-man team is one man short until the next round.
Also, although this isn't a knock against Resistance itself, people actually talk on Xbox Live. When I play on PSN, it seems like a headset is more of a peripheral than an expected piece of the online experience. I guess it's because Microsoft includes a headset with the 360, but it really does make team-based games like this more fun.
Edit: It must be said that I'm not knocking Resistance 2 (I don't even know that much about it), I just prefer Gears' general play style. The coop looks pretty great, though.
Question though: Do we know how many players R2 supports for coop on splitscreen?
