Left 4 dead. No contest at all. Now I'm not saying Resistance doesn't look great but valve (and any game they've bought from other developers/modders) have turned out to be the defining games in FPS genre (half-life 1/2, counter strike, team fortress 1/2, portal etc). Valve quite literally are the best FPS developers in the world.
