My favourite work mouse is a Logitech MX Anywhere 2. Good form factor, and switching between smooth and clicky scroll wheel is good.
Oddly enough, I have not been able to figure out the scroll wheel on the MX Anywhere 3 when tried in stores. They are either clicky, or they are smooth, with no obvious way to switch between them. Sounds like it's supposed to be autoselecting, but maybe this selection mechanism is just prone to failure.
