What do you consider to be the "Goldilocks" distro? the one that balances ease of install and use, up-to-date, stability, speed, etc... You get the idea.
I'm not a newb, these last few years I've lived in the Debian and derivatives side of things, but I've used RH, Slackware, Puppy :), and older stuff, like mandrake/mandriva and others. Never tried Suse or Arch, and while Nix looks appealing, I need something to put in production rapidly. I have tried Kinoite in a VM, but I couldn't install something (which I can't remember), and that turned me off.
Oh I'm on Mint right now, because lazy, but it's acting up with a couple of VMs, which I need, I really don't have the time or desire to maybe spend two days troubleshooting, and I'm a bit fed up with out of date pkgs.
For me it was Gentoo. I am not sure what it is but for my work it just works better. Tests shows it runs faster for my work and comes with all the tools I need to compile things. I really like the package naming scheme and use flags. I also like the custom-ability of it as well. Tried arch and others but hated it.
Also I think the documentation on Gentoo is insanely good.
My main distro is arch but I installed gentoo on a spare laptop and im really enjoying the granular control and the choices available, like if I want to use the binaries I can, or I can use a bunch of USE flags, it's very nice. Emerge is slightly slower than pacman for me but I can live with that. I should learn to write some ebuilds though.
