It depends! You’ll get a lot of recommendations. And they’re probably good recommendations. But there are most certainly Distros out there that are very simple. I would suggest you don’t be afraid to Distro Hop until you find one that you really feel at home on.
If you’re looking for something that’s simple, out of the box, and out of your way, I’d avoid anything Arch based. Ubuntu or Debian based Distros will have the most documentation and therefore minimize the amount of time you spend looking for answers, however, Fedora based Distros, in my experience, are rock solid and sit comfortably between stable and the bleeding edge.
My comment wasn’t “Linux works perfectly in every single regard.” It was “Linux isn’t hard to use for the things that do work on it.” I’m well aware Linux isn’t right for every use-case, nor did I say it was, I said it wasn’t hard to use. Compatibility is a separate issue here.
