I am running - and strongly recommend - Linux Mint Debian Edition (LMDE). https://www.linuxmint.com/download_lmde.php

For the past several years, I was running Debian stable & XFCE. It is a great combination. However, I started teaching technology (programming, Linux, and maker-space tech, like laser cutters & CNC routers), and I wanted to see how close I could get to an "easy button" interface, paired with a principles-driven, highly stable base. I gave LMDE a try, with an open mind, and was seriously impressed.

Linux desktop environments have come a long way, and Mint - with the "start" button (with application quick search), window management, "sane" defaults - it just works.

I will also mention that the Software Manager perfectly blends Debian source packages, and FlatPaks. From my experience, nearly all software that I want to install on it "just works" by searching for it. Those that aren't available there, it seems that downloading a .Deb to install it "just works" as well.

As background context, I have used Linux for 20+ years (Mandrake, Gentoo, RHEL, CentOS, Ubuntu, Debian, and now LMDE) - LMDE gets my roaring endorsement, and I think more people ought to check it out.
