It's mostly CS:GO these days (especially for the competitive scene).
I'm not too sure how Battlefield 4 is going but it seems reasonably active.
If you're not after competitive play then TF2 is always active and fun.
Quake Live also just moved to Steam instead of being a browser based thing, and has had a huge surge in the player-base because of it.
If you wanted to duck out of the FPS genre, then the powerhouses in the competitive scene at the moment is League of Legends, Dota 2 and Hearthstone.
