The Wire is my all time favorite. Currently watching The Shield and while it’s not bad, it’s more of an edgy Law and Order type cop show.
I don’t think anything truly measures up to The Wire but just wanted to hear about anyone else’s recommendations.
Crime shows: Breaking Bad, Better Call Saul, Mind Hunter, Homicide: Life on the Streets
Sci-fi: Travelers, season 1 of Altered Carbon, The Expanse, Firefly, Stargate SG-1
Comedy: Limitless, Community, Better Off Ted, Archer, Arrested Development, King of the Hill
I’d add Andor to the sci-fi section, it’s exceptionally good.
