Agreed, Ubuntu is poorly engineered, they still use some sysv init scripts behind systemd units, which is embarrassing, and I have never managed a successful update. Fedora is great, I did not have half the problems with it that I had on Ubuntu. Every single update went super smooth. The one downside with Fedora is that you don't really have LTS and there is no rolling releaste that is intended for daily use, but otherwise it's perfect.
