I've installed Linux Mint Debian Edition onto one of my machines! I have been using Mint (the one made using Ubuntu) for about a decade and I'm happy to finally cut #Amazon out of the loop.
Linux Mint Debian Edition (LMDE) feels almost exactly like Linux Mint. The only difference I've noticed is that it asks me about the GRUB bootloader more at setup than I recall from Linux Mint.
If all continues to go well with my first machine, I'll be switching the other machines to Debian Edition, as well.
I had a hard time finding information on the differences between specifically Debian and LMDE online that wasn't just AI-generated clickbait garbage, but I have the general impression that LMDE has more set up for me at the outset, which is what I prefer.
