What’s holding you back from using Debian instead of Ubuntu? I found Debian to be relatively the same experience as using Ubuntu. NixOS seems interesting, but I honestly need to learn how to use Arch more first.
I’ve always percieved Debian as a more dull & outdated version of ubuntu. Bear in mind, this is only my perception. I like to have the latest and greatest, I like things working out of the box, I like new technologies such as Wayland and I think debian appeals to the “slow, stable and .conf-only” people.
Though I belive that debian ideals are more in line with mine than a company driven distro such as Ubuntu or Fedora.
Honestly I can say that Debian has improved a lot since then. I was a Ubuntu user for around 2-3 years and thought the same thing about Debian until I realized I was just too lazy to switch haha. I use KDE for my desktop and everything is smooth. No tinkering with .conf files or anything, just install it.
Unfortunately, I use a NVIDIA graphics card and I will say that Wayland and NVIDIA don’t seem to mix well. I run X11 instead and it works fine but it is a little slower. Definitely buying a AMD card after my current card meets its EOL.
