I have Arch on a 2013 mbp and it has served very well for years. I think I had to do a little work getting the backlight controls bound to some hotkey combos, but that might depend more on DE than distro. I’m probably going to put NixOS on it, since I’m not using it as my work laptop anymore. Use whatever you want! Debian is always a pleasure, too, in my experience.
