Get a G36. Cool people get G36's. That's why I have 6 of them ....
Only kidding
Just get out there and play a game, you'll get to see what everybody uses. Some might let you handle their gun, see how you like the feel. I don't mind letting people test firing mine anyway. You'll get a hundred different opinions and then some. Take what sounds good to you and roll with it. Just don't go grabbing people's guns without them knowing
