When I used to maintain a linux machine about 10 years ago, upgrading the kernel was a huge pain on a fedora system (basically required reinstalling the entire OS IIRC) but could be done using the package manager on ubuntu and thus was incomparably less painful. Has this difference gone away?

I never directly did that, my experience was that major version upgrades on ubuntu rarely were painless and on fedora they mostly worked.
