Last time I wanted to try Fedora, it didn't ship some packages I wanted to use that Debian sid shipped, and Debian sid is similarly up-to-date in many stuff (they don't ship plasma 6 yet though, even in sid).
I think Debian sid is underappreciated as a decent rolling release distro. I get that Debian doesn't advertise it that way, but it virtually never breaks for me.
This is the problem, people are recommending Debian-family for desktop.
I don't think people are really talking about server linux, that is almost a solved problem.
