No. openSUSE Leap is what centos was before. A community version of the enterprise distro. And unlike redhat, suse is actually moving towards converging the leap and enterprise codebases as much as they can in Leap 15.3

Yup, the only valid complaint I've seen about OpenSuse is the lower support window, "at least 36 months" for any major release.

I think most of the complainers don't realize how easy it is to upgrade OpenSuse compared to CentOS. It's like night and day. SLES also has kernel updates with no reboot and an immutable root version. Basically / is read-only and all patches are applied to a new snapshot that is mounted at next boot.

CentOS Stream is at most a couple of months ahead of RHEL, not true for Fedora.

you can't compare tumbleweed with fedora since fedora has "major releases" and a support window. tumbleweed is basically on the edge (with transactional-update support) i.e. there is no "system upgrade"
