GNOME is doing really well at building a large set of applications that are well designed and integrate well with GNOME. Libadwaita makes it really easy to make apps, and it makes it really easy to make UI that is simple and easy to use. They also really try to support developers with developer tools, their GNOME Circle program, and this TWIG series providing new users. It’s clearly paid off, as there are tons of really good GNOME applications with more being released every week.
