Lethal efficiency all the way. In most games in fact, not just FPSs. I just love that feeling of taking someone down in one shot, preferably with them/their allies having not a clue as to where the shot came from.
That said, I also often play a bit of brute force in Battlefield games, opting for anti-vehicle weapons... in BFBC2 in particular, there are few things more satisfying to me than taking down a helicopter with a bazooka. There's a lot of satisfaction in tagging it and sending out a tracking missile knowing the pilot barely has any chance of avoiding it, but the most satisfying feeling was this one time...
Atacama desert, I was in a building near a flag point... enemy chopper is flying above us, showering us and the friendly tank with missiles. I'm in a building, the chopper has no clue about me, I can hear it flying above though and I know he has to take a wide circle to keep himself moving while he reloads. So I wait, looking out the window with a CG, waiting. Just as he comes into sight, I take a quick aim and take it down with the first shot. Just loved the feeling thinking how much of a surprise it was to just get shot down out of nowhere without any warning
I do enjoy squad-based breach-and-clear, but that requires good teamwork and sadly isn't always an option. Still, I much prefer providing sniper support overlooking wherever my team is going and taking down anything in their way, guardian angel style
