I personally think the Microsoft Mice are better for gameing. I have had 2 logitech mice before (they were cheaper than Microsofts at the time so I bought them for my kids) and they were not as good as the microsofts mice I was using. I use the 'Microsoft Intellmouse Exporer 3' it has the forward and Back buttons on the left hand side (for your thumb to use) and is good for gameing.
ie: Left button=fire, Right button=jump, Back button=prone (lie down) and forward button=throw grenade! So when you are running you can easily jump, throw a grenade then land in the prone position!
