You are mixing a lot of history there.

Red Hat had packages but not package management at first. However, the same is true of Debian. It depends when you used them.

Red Hat Linux branched into RHEL (corporate) and Fedora (community).

SuSE went down a similar road to Red Hat and has both OpenSUSE and SLE these days. Fedora is less corporate than OpenSUSE is.

Debian is still Debian but a bit more pragmatic and a bit less GNU these days (eg. non-free firmware).
