G9 is my favorite. I had the Razer Lachesis, Copperhead, and used the G5 and I prefer the G9 over those. It can be uncomfortable for normal use, but for gaming it's my favorite so far.
I don't have them anymore. I didn't really like the Deathadder, the Lachesis was a nice mouse though. doesn't track very high off the surface at all. My friend has a G5, and it's not a bad mouse. I don't like how soft the click springs are though.
errrr i hate them all, they are horrible im sorry but their disgusting errr
I own the Logitech MX518, before this I owned a crap mouse , ever since my friend swoped me an 8th of smoke for the Logitech MX518 i have OWNED so many people online some thing I use a bot.
I use to play with my fingers on my old mouse because it was crap now i use my hand and i freakin pwn
i highly suggest the g5 by far... i love this mouse and how you can change the dpi with 5 different settings... i usually leave it the same but when someone else wants to use my computer they know how to make it move slower lol plus for gaming its really accurate and my old mouse used to move by itself.. not this one!
