Why do they keep marketing Debian as a different OS? It is literally just Linux and some GNU system components cobbled together.
If I suggest running Linux to some of my friends, they'll immediately disregard it as something they wouldn't be able to use, possibly because they know I run it and associate it with being a techie. I suspect I would get a very different reaction if I showed them something like elementary OS without even mentioning the word Linux.
That is not true for Debian. Some packages (like the .deb file for Chrome or VSCode) should work on any distribution that supports dpkg, but there are many packages that break compatibility between Ubuntu and Debian. Thus Ubuntu isn't just a customized Debian; it's a customization that creates a distinct operating system.
For many people in that audience "Linux Distro where the latest CUDA just works" is a huge selling point. That is unfortunately not guaranteed to be true of Ubuntu, necessarily, although things have gotten better.
I just switched to it recently and am very happy, it feels like it was perfectly designed for how I use the computer.
It seems to work very well on my laptop. I would say it is the first real innovation in distros in years.
