My current mouse is certainly the best I’ve ever owned: The Razer DeathAdder Chroma
The sensor is fantastically accurate - I’ve never had any tracking issues and, probably one of the most important factors, is that it is very comfortable to use.
The best mouse I ever owned is the Microsoft Habu.
I loved that mouse so much but after years of use the cable started giving problems.
This is the dream mouse to be honest, want is so badly!
It is an amazing mouse indeed!
I used an MX master for years and absolutely loved it. Then i decided it was time for an upgrade. Ordered a Logitech G903 but was told they didn’t have stock and I didn’t want to wait for stock so I opted for the G703 instead. I absolutely love it. Precise as they come and very great to hold. I will be saving up for the wireless charging pad. 
The one I have now, Steelseries Sensei. Only issue is in a (stupid) fit of rage I smashed the shit out of this one so the left click doesn’t “click” anymore and is extremely sensitive. Sadly I don’t think they make this model anymore and the new version is way too expensive.
I read this as Microsoft Haibo. 
I’m still using my deathadder 3.5G (Think it’s the second one they came out with), tempted to try out a new one. I’ve been eyeing the Rival 600.
Couldn’t find any decent pics, but in the 90s, I had a 5 button logitech ball mouse, no wheel (pre-dates) that I used until it died. I could do a 180 in Quake 2 with a quick flick of the wrist, something that is lost with optical mice.
No, I wouldn’t go back to ball mice, I still hate cleaning the gunk out of my trackball… But I do miss that mouse from time to time.
I kickstarted “The Z” from Swiftpoint.
Slowly I’ve been configuring the various buttons to my liking and it’s been amazing in Warframe.
