I started with an mx 518 and imo, is a great mouse but I wanted more buttons and a little more comfort in my palm.
I have big mits.
So I settled on a mx revolution.

Although this is not specifically a "gaming" mouse", it has served me well. It holds a real good charge and slides best, I find, on a mouse pad.
The design fits comfortably in my hand with the thumb wheel being in a nice position and allows me to assign up to 13 commands which is just a personal preference. I love that I can do that with this mouse.
However, the one thing I wish it did have was dpi on the fly but other than that it continues to perform for me.
I do miss the dpi on the fly though and so I'm kind of shopping around myself as well and I gotta say, That cyborg rat looks absolutely bad azz!
While I do appreciate the cool look factor I'm more interested in how it preforms and fits/feels in my big mits. I got lucky with the weight on my mx revolution so the ability to change the weight of the cyborg is attractive to me as well.
If it runs anything like it looks then it would be a grand slam for me so I'll definitely be looking more into this bad boy.
Thanks for posting this one C_Gibby.
