I also tried to avoid maintenance a lot with XFCE, but part of the problem is that I could never get it to look exactly like I wanted. There were always some minor GUI bugs that irked me to no end. Add to that, there were some weird inconsistencies because for a long time there were both GTK2 and GTK3 programs running at the same time and they didn't look quite normal.
Then there was the problem of those new-style GTK interfaces with just the hamburger menu, and not all programs were like that. I tried to fix that too somehow by moving to other Window managers but there was always some weird problem.....arrgg I LOVE linux, but (I hate to say it) MacOS just looks nicer with less fiddling.
