Fedora also has ThinkPad compability program and a nice way to install/update Lenovo drivers.

The problem with Ubuntu, as other mentioned, is that you get ancient version of some packages. Fedora is nicely up to date.

Is this actually such a big point? I feel like (subjectively) on Ubuntu everything gets updated just as fast, and even if not, there's a new full release every 6 months. Or is this actually rather slow in comparison to Feroda?

I've also only used Debian based stuff my whole life and even moving from apt to dnf or whatever it was causes too much friction for me haha, though it's not that bad obviously, if I really would see the positives.
