best mouse I've ever used: haven't missed a shot in rust yet.
Sensor wise, there are a handful of worthy ones. I own many mice (DA 2013, G400s, SS Rival, RAT 7, Mionix Avior, Roccat Pure, G502, Zowie FK1, MX518, Naga). FK1 is super light, which is why it's tops for me among other reasons. I will say the G502 has a ridiculous sensor, but i found it to be too heavy.
Again it depends on grip, but I use a claw.
