For example Red Hat Enterprise Linux or SUSE Enterprise Linux.
I’m considering switching to RHEL, to get a “professional” Linux, since it’s free if you register an account, but is it worth it?
Is the experience very different from Fedora?
More than a decade ago I bought SUSE enterprise for a couple of years just to support the project. Never needed any assistance so I’m not sure about a different experience. BTW The box was nice 🤣
