I’ve dabbled with Linux over the years, first with Ubuntu in the early 2010s, then Elementary OS when that dropped, and a few years ago I really enjoyed how customizable the gui was with Xubuntu. I was able to make it look just like WIndows 2000 which was really cool.
Which current distro has the best GUI, in your opinion? I find modern Ubuntu to feel a little basic and cheap. I guess I don’t really like modern Gnome. I’m currently using Windows 10 LTSC which is probably the best possible version of Windows, but I’d jump to linux if I could find a distro with a gui that feels at least as polished and feature rich as Windows 10 LTSC.
Distro doesn’t really matter nowadays. You can get all desktop environments to work on most distros. Especially the big players like KDE, Gnome, Xfce have hundred distros they are shipped with by default. Most big distros have versions for each of the most popular desktop environments. Therefore, I would suggest that you look for the distro which fits your needs best and then install the desktop environment you want to work with afterwards, if there isn’t a flavor of your distro that ships with it already.
