Logitech is probably the best choice. G600. I use that for my MMO's. Have never been impressed with Razer's. Too each their own thou.
It has nothing to do with accuracy. I used the Naga for an entire expansion cycle in WoW and I never stopped having issues with the sensor. It was extremely sensitive to dust, so anything at all on the lens caused the cursor to stop functioning all together. The cursor would walk up the screen on it's own, and worst of all the x axis stopped functioning all together. Cleaning wouldn't fix it. It just gave up the ghost. That was the last straw for me with the PTE sensors. I own one mouse other than the Naga with a PTE and it's trash (RAT 7).
whats PTE?
Philips Twin-Eye. It's a doppler type laser sensor.
those buttons on the m95 look horrible to use o_o
I say either M95 or Logitech G602. Do NOT even consider ANYTHIING that uses the Philips Twin-Eye laser. Its probably the worst sensor Ive ever used.
And that's why it's important to take all mouse-related advice with a grain of salt - it's all a matter of opinion
