I had a huge problem with Arch because of the rolling release deal. I just can't handle the responsibility of updating packages every single day, even with automation.
When I install an operating system, I want it to just work, and I want their repositories to have lots and lots of software. Most distros do this, but none do it as well as one of the major Debian-family distros like Ubuntu or Mint. Fedora is quite nice as well, and I could probably daily drive it without issue, I just see no reason to change over to it since Ubuntu has me totally covered. And it is basically like this for me with every other distro: I have to think, "why would I switch? What benefit would it provide me over what I have right now." The answer is always "nothing important," so I stick with Ubuntu.
I considered using Guix because its package manager is truly a revolutionary new technology. But using it as a package manager, I can see a lot of the packages and default configurations just aren't quite to the point of "just works" yet. Still, I hope someday to switch to Guix as my daily driver.
