Third person makes it a lot easier to assess your surroundings. In real life, your eyes can move around in your head and give you a better view of your surroundings. In real life, your ability to lean around a corner is not statically set. In real life, I'd do a damn good job of having as little of a profile visible when looking out of cover if I think someone is around a corner, or in a building. Sure the engine lets you move your head around freely, but it doesn't allow you to keep in cover and spy on people. Hell, the game also doesn't even allow you to move without making any noise at all. I'm for third person.
