How to handle movement in a multiplayer FPS?

Hey!

I was wondering what would be the pros and cons of using rigidbodies to move the player in a reasonably large scale FPS multiplayer game. Would it be better to make the movement similiar to Unity's FirstPersonController that doesn't use rigidbodies or create a physics-based movement using rigidbodies? Mainly I'm interested in differences between performances and overall possibilities/feel of these options.

Thanks in advance!
