True, but it is also completely different use cases and they have different goals.
Windows on a 2-in-1 is also not as good as an iPad. They are desktop OS’s with tablet functionality as a nice to have. They will never be as smooth of an experience as a mobile-first OS.
The trade off is 100x better compatibility with many apps, especially FOSS. inkscape, krita, KiCAD, FreeCAD, coding IDEs, MATLAB/scipy, games, etc… They are all available out of the box without a mediocre mobile port.
The flexibility to functionally use it as a full-blown computer (and not reliant on a monopolized, centralized app store) is the reason you get it and not an iPad. Of course it won’t be as good as a tablet because it wasn’t made for that.
You can also say “the iPad will never be as good of a drawing experience as a dedicated high-end drawing tablet.” Like of course. That isn’t its function and goal.
