"... Desktop development for Linux is a minefield - and Linux UIs really lag behind Windows and macOS. ..."
In what respect does the UI 'lag' ? It depends what you're looking for in your UI. Admittedly, you have to choose the desktop that suits you from a large number of available choices.
I like a 'rock-solid' traditional UI that looks crisp and presentable without a lot of arty-farty eye-candy. Trinity Desk Environment (a fork of KDE 3.5) does that for me, and provides a huge range of GUI tools and applications. Other tastes may vary.
Not having to run 'badly-written' corporate applications, as mentioned by previous posters, most of the Windows-only applications that I need run perfectly on Wine. A VM of W7 or XP takes care of most of the rest.
