Some Razer mice were somewhat good in the times when the sensor mattered, with the rest of them being absolute garbage (starting with the Copperhead which barely worked). Today there's a ton of niche manufacturers with great internals that will exceed any requirements you might possibly have.

If you're really interested in FPS performance and not just the brand, choose for the ergonomics first, it's not possible to recommend anything without knowing your play style, hand size etc. The shape and weight you like, and complementary feet and mat with the exact static/dynamic friction you need. Then check if the internals are good enough (they likely are) and whether there are any firmware issues like extra jitter on flicks or unavoidable debounce lag, then look at the required software. There's a ton of mice with excellent performance that are configurable without ANY software.

This is unfortunately why I keep buying the Razer Deathadder Pro. It fits my hand perfectly and is super accurate. I hate their software, and the company, but the performance and ergonomics of the mouse are worth it to me.
