I've moved from Ubuntu to Fedora and it's been more stable while also being more up-to-date without rolling-release distros headaches. Strongly recommend it.
I gave Fedora a try some years ago (4-5?) and had a couple of issues with nvidia drivers. Whats the status these days? I also have a long history with debs, so going to rpm is a mystery for me :)
Also to add. Fedora has a 6 month release cycle for versions and a version is supported for about 13 months I think.
But during this time they regularly update packages. My kernel is always the latest version.
But I trust it because Fedora has a massive testing automated update and testing system. Every package is thoroughly tested for regressions and other things.
https://bodhi.fedoraproject.org/ to look for yourself.
It is also integrated into their bug and other systems so it's a very well oiled machine.
It's been rock solid stable for me and I've been running it since 35. And upgrades are super easy.
There is also COPR which is their AUR/PPA hybrid system that lets them provide a way for users to setup their own repos but build using Fedoras learnings and systems. It's pretty cool.
Also with `dnf` RPMs are as easy as DEBs. And some of the commands are similar.
I find dnf is even smarter and better at managing dependencies.
I only ever run 2-3 commands. `dnd install` `dnf update` and `dnf remove`. Update handles the repo refresh and actually updating packages. And force refreshing repos you just add `--refresh` to the command. Otherwise it does it every few hours on its own (the refreshing of repos, not installing updates)
Fedora is a breath of fresh air after decades of Ubuntu, and then Manjaro. I wouldnt go back and I have used Ubuntu since 5.04 til 22.04
Nvidia is still nvidia -- with newer kernels you may occasionally find some build problems for their drivers. Fedora amplifies this by using such recent kernels
There are better packages/attempts at handling it, but I still find myself switching it to an LTS kernel if I have Nvidia or ZFS involved.
