I divide mice into two categories: hardcore and general Hardcore is a mouse that has perfect 1:1 tracking, suitable for very competitive gamers that compromise nothing and want their equipment to be goddamn perfect. This includes Deathadder, Zowie eVo mice, CM Storm Spawn, Abyssus, G400 and only a few others. Most of the public would be OK with general mice, which have "some" problem whether it's a teensy bit of acceleration or slight jitter or anything that prevents a perfect 1:1 tracking. Most people wouldn't notice or care about it, and so would be perfectly happy with such mice. This list includes everything else, almost all laser mice, Corsair mice, Mionix, Roccat, Sidewinder laser, Logitech other than G400 (MX518 + older stuff tends to be hardcore certified though) basically almost everything.
