To be honest, that's highly subjective and for example depends on what kind of mouse grip you are using, and what your overall preferences are to find the best mouse for you.
I think nowadays basically all mouses are on such a good standard that there aren't necessarily any technical reasons to choose one over the other. Sure, some of the Logitech or Zowie sensors could be considered better, but even for pros, that's barely noticeable.
I think I would rather ask what your aiming style is like? Do you play with a high sensitive? Are you aiming with your wrist or your full arm?
Do you prefer a light mouse, over a heavier, with more control?
Do you prefer using a claw, fingertip or palm grip?
I would suggest looking for something that's most suitable for you and not just something someone else recommended for you.
For my part, I went through my fair share of mouses, but for the last couple of years I'm loving the Logitech G Pro X Superlight with a claw grip. I would like if it were a little bit longer and higher though. That's just because I've got relatively big hands.
