I know I am the only person in the world that did not like Succession but it was too over the top for me. Perhaps it is a satire and I am just not getting it. The characters just weren't believable although the son-in-law (Matthew MacFadyen) is really handsome. It is pretty amazing that he is English. If you just saw him in Succession I don't think you could tell.
The other two I have not seen although I have them on my list on Netflix. Right now I am almost done with Babylon Berlin. I would recommend it (at least the first two seasons). I am waiting to see where the third one leads me. My philosophy has been that often a series is good for perhaps 3 seasons and then putters out. Babylon is so expensive to make I am not sure how long it can hold out considering the current crisis.
