I've used laser mice, optical mice & ball mice. Laser mice are definitely the nicest ones to use. I have the Logitech MX100 (somebody gave it to me
!) I have never had any troubles with it, and it is really good for playing games on. Also, the laser never jumps or anything like an optical mouse does, as the optical mouse may react with patterns/shapes on the surface that you're using it on, the laser mouse doesn't do this =P.
