I know a lot of people who despise GNOME 3 on the whole, but I'm willing to defend it for what it is. If you've ever used a touchscreen Linux device, it becomes a whole lot easier to appreciate what they did with the toolkit. GTK apps just... work on a touchscreen. No modifications or fancy-pants libraries required. They also work really well on desktop too, with nice plump interactive elements that make sense for the category of devices that it's targeting. It looks equally as spiffy at 200% scaling as it does at 100%, and it's snappy as all hell.
I don't speak for everyone, but GTK3 is the unofficial "native" toolkit for Linux. QT isn't far behind (I've been using Plasma since GNOME 40 and it's a blast), but GTK3 just feels... right. Also licensing and custom stylesheets yadda yadda yadda.
