The reason the OCZ Behemoth Double-Laser Gaming mouse was rated an 8 in the comfort test is the fact that it is a little large for my hand and I am used to a more relaxed and spread out hand position like the Razer Diamondback 3G was able to provide, whereas the OCZ mouse had a more tense and bunched up feel to it. The customization of the OCZ mouse was better than the Razer mouse, as it has way more options for what the buttons are able to do, as well as has the ability to create a script for a button. I do prefer the way that the Razer mouse is able to change the DPI settings by holding one of the side buttons and using the scroll wheel to change the resolution setting, while you only have four in-game options with the OCZ mouse.
