MX Linux.
Imagine Linux Mint Debian edition, but it isn't green and there are a lot of useful GUI tools. It's also so near to actually being Debian that you can just install things meant for Debian on it. It also runs a backported kernel for modern graphics driver and chipset support so you get your stability and your performance all in one.
I never considered going back. Lemmy is forward. More power to the users and the community and less from greedy shareholders. This is the way.
