This one really depends on when you play and what map you play on. I have noticed that I see certain names pop up only at the Observatory, others prefer Waterfront. The other thing I have tended to notice is players who dominate at TDM sometimes lag behind at Cap&Hold. For PvP are you asking only Deathmatch, or do you include all aspects? There are some players I see regularly on Freight Yard who don't get that many kills, but help their team by getting quite a few caps.
All that being said, I recognize most of the posters here and would have to agree with Obnautkis, Nicklbackr, and Mtnmagic at the least.
P.S. Is it just me or is there a lot more use of Incinerators and Bonfires?
