It is a matter of taste, nothing against KDE, or the minority role it currently holds on Gtk dominated landscape.

Not sure if it's really minority.

Have been using desktop Linux for almost 2 decades, My last 2 workplaces have been Linux desktop centric. Helped deploy quite a few Linux workstations.

I don't know many people that use Gnome.

Most use either KDE or some tiling WM (or some custom fork of Gnome2/3 that looks nothing like default gnome).

When Ubuntu dropped unity, some people went to gnome, some stayed but at least in my circles most bounced off.

Red-Hat Linux Enterprise, CentOS and Ubuntu, with default window manager, is what I usually find on the customers I deal with.

On the cloud deployments it doesn't matter as they are accessible via ssh and cloud shells, and X Windows servers can be mapped to single windows.

Sure If you are talking average user.

Most of the people that I know that use Linux desktop are developers, and they generally don't use Gnome.

On servers sure its RedHat or CentOs or Ubuntu/Debian

But desktops are Ubuntu variants, then Fedora. Don't know anyone that uses RH or CenOS desktops.
