mamba elite

I need a new mouse mostly for League of Legends. Which would be better and why? The razer deathadder V2 or the razer mamba elite?

So i want to upgrade from a deathadder chroma which had an accident, and since long time i wanted a mamba because heard good things about it was thinking getting one, plus it have nice Led which i personally like a lot plus the elite came out some months ago solving some issues other past...
