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.
I am into KDE Plasma, it works quite well on my distro (Fedora by the way) and one thing that I like about is is that I can make it truly mine. Defaults are nice, however sometimes I think I don't need that or need something else, and quite often I manage to do it to be the most comfortable for me. It's also very customisable and with enough learning you could rice it into quite a lot of stuff, even though I myself don't really know a lot how people do it.
