Title is quite self-explanatory, reason I wonder is because every now and then I think to myself “maybe distro X is good, maybe I should try it at some point”, but then I think a bit more and realise it kind of doesn’t make a difference - the only thing I feel kinda matters is rolling vs non-rolling release patterns.
My guiding principles when choosing distro are that I run arch on my desktop because it’s what I’m used to (and AUR is nice to have), and Debian on servers because some people said it’s good and I the non-rolling release gives me peace of mind that I don’t have to update very often. But I could switch both of these out and I really don’t think it would make a difference at all.
Gentoo for my workstation because I need flexibility, security and stability there and Debian stable for my Raspberries running all the services I need 24/7 access to.
I don’t like all the spin-offs of the major distros. And no, Ubuntu is not a major distro it is based on Debian and they are known for some really bad decisions in past and present, eg: snap instead of flatpak.
