Linux Mint for desktops/laptops (Cinnamon if the hardware can handle it, MATE if it's a bit long in the tooth), and Debian for servers.
I've used several distros (yes, even Arch btw) through the years but I just keep finding myself coming back to the Debian-based ones. I guess I just feel most at-home with the way it has things set up, or something.
Every last post here feels like it's directly calling me out. I hate it, but I also love it.
