Debian is far from difficult but it is certainly not as easy and beginner friendly to install as Ubuntu, Fedora, or Mint or any other mainstream distro (unless I’m using the wrong iso or something). Debian is a great intermediate distro, but I can’t feel comfortable recommending it to newbies until there is a proper beginner friendly guided install process.

I understand and respect the choice of some distros to not go the guided installer route and go with approaches that are more traditional, flexible, and better suited for more advanced users. And I don’t want to see these options go away. But I don’t recommend these distros to beginners unless they express interest in learning/DIY
