For me:
Babylon Berlin intro captures the art, the deco, the decadence and the fear of what the viewer knows is going to come of that time period.
Black Sails just perfect
Raised by Wolves I was hit and miss on this in many ways, but this intro is great - albeit I think slightly misleading as to its overall tone.
Pennyworth I thought S1 was a bit silly, but what an intro.
Happiness This is just fun, and fits the show brilliantly
See also isn't bad
Romulus Very vikings-esque
Song of the Bandits The song on the YT video isn't great here imo, but they actually mix it up in the show proper and use different songs. And some really fit the theme.
