I watched a lot of reviews, and i would personally go for the gila.
1. One of the best looking mice of all time.
2. Awesome LEDs with like 16 million diffrent collors to pick.
3. More comfortable.
It has even got more dpi(8200) than the deathadder(6400 i think), but that doesnt matter becaouse you wont go over 2000(depends on the resolution you are using)
Hope this helps!
