Without KDE, RHEL is GNOME to Hell
RHEL/CentOS has for a long-time been my "go to" Linux of choice.
(IMO, Linux Mint is the only half-way decent Debian-based distro for Muggles)
I absolutely loathe GNOME3. Fortunately, apart from CentOS on my notebook, all my Linux servers are non-GUI (ie headless/SSH only).
MATE and Cinnamon are excellent GNOMEish alternatives to GNOME3, however I switched my desktop allegiance to KDE precisely because of the abomination that GNOME3 was when released way-back-when in Fedora.
So, so long as KDE/Qt remains available for CentOS, I couldn't give a rat's arse whether Dead Rat* deprecate KDE in RHEL or not; I absolutely refuse to have the excrement known as GNOME3 shoved down my throat once again.
*Dead Rat because that's what they'll be after they get swallowed by the Sargasso Sea that is Big Blue.
