You dare defile Lower Decks by calling other stuff “More cannon”! Experience bij, petaQ! 😉
In all seriousness, though, I would say DS9. The first season is much better than TNG season 1 in my opinion - not perfect, but livable. It mostly gets better from there, though like VOY, be prepared for sudden urges for Rick Berman to “accidentally fall out an airlock”, if you know what I mean.
This might be tinted by DS9 being my favorite Trek series, although Lower Decks is putting up fierce competition for DS9’s top spot in my heart.
I like Debian. To save you the misery, though, you should probably just use the OBS Flatpak with it. I used to be a “native” pedant, but these days, I at minimum consider Flatpak a VERY necessary evil, if an evil at all.
