Deathadder or G500 imo (DA for best sensor and G500 for everything else)
Like many here I've had a ton of different mice. I mostly used logitech up to the MX510/MX1000 then I got a deathadder and went on a razer binge with the DA, imperator, orochi and naga. I recently got the G600 and was surprised by it's superior build quality and sensor performance when compared to all the razer mice, except the DA's sensor which is the best of all I've owned. I got rid of the imperator and sidelined the naga for its jitter issues. I returned the G600 as the ring finger button was just too far a departure for what I am use to, especially when added with the 12 thumb buttons, and would give my hand a cramp after 30 min of gaming...otherwise it was really quite good. I exchanged the G600 for a G500 and oh how my hand recognized the shape...so comfortable. As of now the G500 is my default and I switch to the DA when the positive acceleration on the logi gets annoying...and the orochi for laptop.
Here's a few pics to make it interesting....
