@jimnakos @jectoons Yes, +1 with jimnakos; if you already found a bit of comfort zone using Kubuntu, then keep it. It's a good distro.
I recommend also the blog post https://raghukamath.com/setting-up-debian-linux-with-btrfs-kde-plasma-for-a-creative-workstation/ , with a detailed how-to Debian KDE workstation.
@davidrevoy @jimnakos Thank you both for your replies and advice! I take it to heart. I will also take a look at those articles linked and try to make this work soon. Not a fan of the generative ai living in my pc.
