That depends on your preferences as far as the handling of the mouse is concerned. The G Pro X was designed more for gaming, so it's also very light. It just has a completely different feel. Personally, I also like it for office use, etc. But that's really a matter of taste.

I can only agree, it all depends on your preferences - that's why I personally have two mice: an MX Master 3 for home office work, coding etc. and a Glorious Model D for gaming.
The main advantages of the Master 3 are the gesture button and the button assignment per application (although I don't know whether the Pro X Superlight also allows such a profound configuration via the software).The advantage of the Pro X Superlight for gaming mice is the better sensor, which makes for a "smoother genre", especially on monitors with a high frame rate - and of course allows more precise "work" in games ;)
