"Debian - older stuff for stability. Arch - bleeding edge rolling release. Fedora somewhere in the middle." Very true. I would add that then there are a bunch of others that fill the gaps in between. For instance, Ubuntu makes Debian easier and Mint makes Ubuntu more open and TuxedoOS makes Debian/Ubuntu far more up-to-date. Then, CachyOS makes Arch more easy and gamable while Manjaro tries to make Arch more stable. Fedora is a perfect blend but those those that have a beef against Redhat/IBM (USA), OpenSUSE is a perfect blend too of the philosophies of Debian and Arch.
