subjective of course, so [i]my[/i] best gaming mouse may not be best to someone else. For me it is the Razer naga 2013 edition. Yes, I do actually use all 20 buttons on the side and I'm not just saying that. Even when not playing games I have a profile for design stuff like simple commands such as cut, copy, paste, delete, and enter so I don't have to use the keyboard for simple commands when in design programs. Even on web browsers it's nice to be able to copy urls or text in a single button click and as fast as that another button click paste it. Workflow increased drastically =) When gaming I put a ton of useful stuff on the buttons as well. Games like BF4 that have extra add-ons and options it works handy for tossing about health/ammo or switching to different weapons quickly. RPG games it's even more useful as I can put every menu and preset I want on the buttons.

Red dot, fools!

It depends on: a) the game being played b) your hand shape and size c) the way you grip your mouse, and finally, d) your in-game sensitivity. Different mice sensors have different malfunction speeds, different levels of prediction, different levels of acceleration, and different lift-off-distances. The mice themselves have different textures, shapes, sizes, number of buttons and the cord properties vary tremendously! To put it simply, there is no best gaming mouse. If you're looking for a good mouse for a particular game you should consult some of the better players within that community.
