it's a very subjective question, depending on stuff like how much you care to update the system, but I'd say:

you might like https://mxlinux.org/ which has seen growing popularity, it's based on debian stable, but with more up to date software, and ability to use newer kernels in case you need better hardware support for very new hardware

you might also just run normal debian, if you don't care for latest versions of everything... Debian is what Ubuntu is based on, and Ubuntu is very close copy of Debian, except Debian's release cycles are very long, so you'll be running on old software all the time, if you choose debian's stable branch...Ubuntu picks packages from debian's Testing branch, verifies it's good enough, and pushes them to ubuntu users, while debian stable is trying to be "super ultra mega stable", so it takes a loong time until everything's sufficiently tested...but using debian's testing branch is pretty fine (unstable is often fine, but might break sometimes)

and another contender: I feel like OpenSUSE is criminally underrated... as they get their money from the enterprise side of things (paid support for linux servers, etc, much like red hat and others), they don't have any reason to mess with what works, and they've been around for like, over a decade also, I forget how long, but a looong time... it would be a bit different, though, using RPMs instead of DEBs, and such, but one very useful feature is, they have builtin YaST control panel which allows you to, either GUI or TUI interface, do a lot of common tasks, without having...
