While I leave my everyday mouse at home, my current favourite for LANs is a bigger sibling of the Surpassion; the Revenga. Cougar in general have greatly impressed me with the build quality of their mice. They don’t creak or feel like they’re bending under hand pressure as many others do and the buttons don’t feel at all loose or rattly. When I’m clicking any of the buttons, there is never any doubt as to whether I’ve actuated the input or not. This might sound a bit specific, but under pressure in games like CS:GO it can really matter – it’s literally life or death, kind of.
