I don’t think that even 8 years ago, the ‘business’ choices would have been SUSE / Fedora / Debian. If you’re paying for support, then you’d be paying for RHEL, and the second choice would have been Centos, not Fedora. Debian in third place maybe, as it was the normal choice for ‘webserver’ applications, and then maybe SUSE in fourth.
