I have a Logitech MX Vertical and like it pretty well, but the only other vertical mouse I tried was some knock-off from Amazon that died after a couple years.

I have one and I like it Not super competitive when it comes to shooters or anything like that, but everytime I do play a shooter I have no problem with it

MX user here, imo the MX is to bulk for constant FPS. Feels like your throwing a rock around. I preferred the size and weight of the amazon cheapy especially considering how much the MX cost. It’s a nice mouse just not a great gaming mouse for long sessions again just my opinion
