These mice are ideal gaming mice. Of the ones listed, I have the Lachesis. Works with either hand, has 4 side buttons (2 on each side). I have my two left side buttons set to do things like back/forward in browser and jump/crouch in games. The right side buttons switch profiles which I don't really use.
Biggest thing is the two extra buttons on top of the mouse that increase/decrease sensitivity on the fly. Rather, it adjusts the amount of dpi that the mouse uses to go across the mouse pad, so you can go from quick movement to delicate sniping with the touch of a button. These buttons can all be remapped when using Windows, though the mouse works fine in other OSes, you just don't have specialized drivers to allow remapping.
The other neat thing is that the buttons are controlled by hardware firmware instead of software, so all of the features work out of the box in any OS, and the firmware of the mouse can be updated to make changes.
Jam it back in, in the dark.
