What is the best gaming mouse?

i am a fingertip user and i just got a mx518 because a lot of people said it was the best gaming mouse. but when i tried it i didn't like it because of the ridge on the right side makes it so that i have to put 3 fingers on the top and only two at the side. holding the mouse like this gives me less control over it. has anyone else experienced this problem with the mouse? is it normal? am i supposed to get used to it? should i return it or try to get used to it?

i also bought a razor diamondback once because of its touted 1600 dpi and cool neon colored lights. but i returned it shortly after because this mouse felt even less comfortable. i can barely reach the side buttons on that thing.

i feel like i've tried every high rated gaming mouse and found nothing. i finally decided to go back to my 4yr old microsoft optical intellimouse. can someone help me find a better mouse i can upgrade to? what about the creative fatal1ty mouse? is that any good?
