I'm in a similar situation, but I'm pretty sure that when my 2015 MacBook Pro dies, I will still be unable to find a Windows notebook with a comparable touchpad. Running Windows on my gaming desktop is tolerable, subject to the caveats you've outlined. But even with great software, Windows notebooks are still handicapped by poor hardware interfaces. I realized recently when I got a new Windows notebook for work that touchscreens exist and are popular on Windows notebooks because they partially compensate for the horrible touchpads. On my MacBook Pro, I still feel no need to augment the touchpad with a touchscreen.
