I’m not sure I can think of an example beyond lack of software/driver support

General difficulty of use (i.e. how many things do I have to read and do for something to happen the way I want)

And I want libraries to be officially supported, whatever that looks like, mainly so I don’t have to use workarounds or unverified sources (I don’t want to be using lots of Arch’s equivalent of PPAs, for example)

my distro has Polish, but translated into English cos I can’t read Polish. Very user-friendly
