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?
And RHEL itself is free for individuals.
RHEL is (was) great, but the ‘free’ thing is an absolute annoyance to renew periodically and - importantly - the subscription crap is needless hassle. I use Rocky for the dev stuff and RHEL when it’s prod customer stuff. That spreads out the infrastructure plan to be 1. everything working, and then 2. glue in the subscription bullshit.
