@rindi I want to address your misconception that Rocky doesn’t have live images. See this post: [Start Here] Rocky Linux Resources and You that shows live images for Gnome, KDE and XFCE downloadable from the Alternative Images section on the Rocky website.
Debian and Ubuntu are also just as much server OS’s, as they can be desktops. Debian, just like RHEL doesn’t have the latest and greatest software. Ubuntu in some respects can also be by using the LTS releases.
All distributions can be utilised as desktops, including RHEL, Rocky of which it is based - there are additional repositories that can be used. Just because they don’t have the latest software, doesn’t mean a decent desktop cannot be made and used. Plenty of people do that already without any issues whatsoever. Those who wish for the latest and greatest software - or bleeding edge, use distros like Fedora, Arch, Gentoo if they wish to compile everything themselves, and other similar distros.
People choose what fits their situation best, and that doesn’t mean that RHEL or Rocky cannot be, or should not be used as desktops. That’s purely something of a personal viewpoint.
