I used to have a spreadsheet of all the packages I use and their availability between distros. I think I'd like to update that and see if Alpine is viable (I like Fedora but it's getting a bit stale how good and stable it is, so I'm kinda looking forward to trying something new)
Personally, I'm interested in, and prefer the stable version, where that is available, with the only exception being OpenSUSE where I'd pick Tumbleweed any day of the week because it had some packages I wanted that weren't on Leap yet.
