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.
I eventually decided on openSUSE Tumbleweed for a few reasons: rolling release, because I like to stay up-to-date; non-derivative, not a fork or dependent on other underlying distros; European, for (perceived) privacy reasons; a relatively well known and large distro with a decent community, for troubleshooting reasons; backed by a company, though that has both its ups and downs; lastly, support for KDE Plasma.
I actually had trouble finding a distro that suited all my criteria at the time, but openSUSE is good enough for now and I am pretty much satisfied.
