SteelSeries Kinzu Vs. OCZ Eclipse

Currently i have a 12 dollar logitech custom mouse. I can polay fine but i have heard that the mouse does make a big difference. Now i want you guys to help me choose between one of the two mouse.

THEN once you tell me which one of those would be better for me i would like you to compare it to the Razer DeathAdder and tell me how big of a difference in performance or exportability i would experience.
