Hi: fact is though it comes down to two things:
1. how the mouse
feels in your hand...if you're not comfortable using it, then
it's not a good mouse for you no matter how amazing it is, and
2. the layout of the mouse. make sure you look at how the buttons are
arranged on the mouse...again, if they're not to your liking, then it
could be the best mouse in the world and it will still suck for you.
anyhow I strongly Believe that the razer are a good mice & logitech are better (end of story)
I'd advise getting either:
2. g500 (if you don't like the way the 9 series feels)
3. Logitech MX518 Optical Gaming Mouse (old, but still a solid mouse)
