Logitech MX Anywhere. Been using bunch of them, different generations of it, along with my family for the past years. I just have to say they are great at mouses. The internal battery is long lasting and rechargeable. Connectivity is amazing as you can switch computers/devices (3 maximum) with the press of a button and you don't need dongles for it (if they are Bluetooth enabled). You can also have functions in it which you can customize depending on the workflow or work type. So I do recommend it. If you use a MX keyboard also along with it, it doubles the fun.
