The only 3 GUI applications I use regularly are Emacs, Firefox and XTerm (which, like Emacs, has amazingly low latency). All via a tiling window manager (StumpWM).
I also use Signal Desktop, which is a rather plain Electron app.
For some imaging tasks, GIMP and Inkscape are great. GIMP gave birth to GTK, one of the two major Linux GUI toolkits.
Since the desktop ecosystem is very fragmented, I don't think there are any great GUI applications in Linux. On Macs, things are declining now too. A lot of the GUI innovation is happening on mobile.
In Linux, niceties come from CLI and whole OS, like Nix.
