I own the Deathadder Elite but everyone I know who owns some kind of Razer mouse or keyboard tells me I should've gotten the Mamba Elite. It's been nearly 2 years now since I got the Deathadder. The only reason they say it's better is because of the Lamborghini grille thing on the front.
I'm pretty happy with the Deathadder but I'll be upgrading by the end of this year.
Is the Mamba a worthy upgrade or should I go for some Logitech mice. I've seen some reviews and they handle pretty well.
P.S. I play a lot of FPS and casual singleplayer games.
