I have an 8 core CPU, but I have to admit I don’t use any DE.
Updates can take several hours if I don’t upgrade for a while, but PC is usable during them (you can set number of build threads).
Manual intervention is what I’ve said needed way more in Fedora, which left me without any video after updates, or Ubuntu which broke integrations or replaced my software.
Gentoo just… is.
There are sometimes updates that would require intervention if you do something special, nothing too difficult though, and you get a link to Wiki with working solutions.
I need to donate more money to that project.
It’s usually the llvm that takes forever, then Firefox, then LibreOffice.
You can actually pull binary packages in Gentoo, if you are into that, and update like any other system.
