It’s in the eye of the beholder, of course. But it would be great to see some solid recommendations.
I like the look of KDE Plasma the most.
GNOME vs KDE gang fight has been summoned.
The look of GNOME isn’t the problem of GNOME. ;-) I’m not a good citizen right now.
Absolutely. GNOME often looks better, but it just doesnt work. Basic things everywhere are removed or not added.
The thing I’ve learned in the many years of watching this fight is that the things Gnome people (of which I am one, though I have immense respect and appreciation for the KDE project) don’t like about KDE tend to be the things KDE people like about KDE and vice versa.
