Best Desktop Mouse

So my Performance MX is finally ready to be replaced. Longest I've ever had a mouse (15 months). I've managed to rub the mouse smooth and it just doesn't feel right in the hand anymore.

So I was hoping for some suggestions as to what is the best mouse out there now. Is the Performance MX still king? I have no issues with it, but I would like to know if there is anything better, yet. Just for comparison's sake, my last three mice prior to the Performance MX were MX Revolutions, which I still contend is the best mouse ever made.

I only do basic gaming on my PC (Minecraft, Portal, Dungeon Defenders, etc) so there is no need for a crazy Razer mouse.

So, any suggestions?
