People have different tastes and opinions, and I don't remember how GNOME looked in 1998, but KDE 1? 2? wasn't so great imho (saying that as a huge fan of plasma, and intermittent KDE user for the last 25y).
I used enlightenment for a bit and was very happy with it - just like some things on a desktop at home don't matter, but do on a laptop. I've more than once mangled i3 and gnome or xfce or kde together to have the "desktop environment" things like wifi and power management and so on.. whereas in the 90s on a desktop I cared about neither of these things.
And while this was all very much a long time ago, I don't see how enlightenment would have changed - it's just a bit barebones compared to a DE, just like i3.
> KDE 1?
Yeah, compared to Win 95 at least, it looked interesting in a positive way...
Problem was: Whenever you clicked on something, some message box appeared, with some one-line error message that contained the word "unknown" or "unexpected"... :)
KDE1 had some very nice themes! I remember using one that drew inspiration from the visuals of Bryce on the Mac. Dark mode theme - and animated window titles which would scroll gently if the window title was too long to fit.
