Never ever heard of your description of RedHat and why it would be a good reason to use them.
10-15 years ago i tried Red Hat / Fedora and it wasn't great. I than also tried debian and it just worked and was easy to use.
Now, i'm not looking for support much. I prefer the base stability of debian/ubuntu. Haven't looked into RedHat a long time and i also don't see any big reason for it.
