I use Slackware because, in my opinion, it is simple, easy to understand, doesn’t get in your way, and strikes a good balance between being up to date, stable, and bug free. I also have it set up how I like it and don’t feel like installing something else. Honestly, the lack of dependency resolution has really not been a problem. By default, Slackware comes with a lot of libraries, and sbopkg (which builds SlackBuilds from slackbuilds.org) can do dependency resolution, as can some third party package managers. And with appimages and flatpacks, this is less and less of a problem.
That said, I use Manjaro on my Pinebook and am perfectly happy with it, and I’ve used Debian in the past too.
<rant> I use RHEL at work and it’s not bad, but I don’t really care for it. It feels overly complicated in terms of configuration and daemons running, and I don’t know systemd that well. Although I think this is mostly the fault of our satellite server, “dnf update” breaks on me at least once a month. Also, some packages are just plain archaic, and didn’t even update from RHEL 7 to 8. And I can’t seem to wrap my head around source rpms or how to make rpms. Slackware and Manjaro use straightforward build scripts. </rant>
