Mint - Firstly Wayland support, but that’s been said before.
But one small annoyance is that they ship with a version of synaptic in the repos that doesn’t allow software upgrades. The reason for this is that they want you to go through their update manager (which doesn’t work for me, but eh). But seriously, for an OS and ecosystem which is supposed to be pro-user agency, why arbitrarily restrict people like that? I end up having to pin a specific version of it.
