I'm generally speaking about the state of X11 vs macOS or Windows. Like configuring multiple monitors, getting your mouse working just right or other tasks that sometimes can just be freaking difficult with X11. But not wanting to go into that flamewar now. I would be surprised if it's better than Qt, in fact I know it's not. GTK+ also has had a lot of work during the years, but they have dropped the balls many times over major revisions, so in that sense it might be a better framework than GTK. But then again, it all comes down to who uses these. Qt is widely used beyond Linux in application development, and modern QT is actually a very nice development environment. Wayland is also in a state of not-complete. What I'm trying to say here is that the display technologies behind most Linux environments are not in a good state. They work, yes, but some things just don't work or are impossible to setup compared to eg. macOS or Windows. This is mostly due to open source fragmentation and legacy code in my view, and the fact that everybody and their brother would rather fork out their own desktop environments than decide to make couple of good ones, but hey that's Open Source. Also missing commercial support of course.
