Whenever I tried to move away of gentoo I have found only pain.
Looks good first few days but pretty soon I find issus I don’t want to deal with. Additionally, solutions are made by much less knowledgeable users, so even solution is hard to find.
I use gentoo because it works and I know how to fix (without reinstalling).
I have mint on one desktop, it is so nice… but I use it only occasionally (for gaming and deep learning) even font rendering is not what I like.
You can try Debian Testing (or Unstable) whichever is rolling release, that’s closest you will come.
A lot of people like Fedora… so, maybe…
So… shop around but you will be back, it is like going from Subaru to anything else in the same price range or cheaper. Not possible.
