What network or streaming service is best for your Period Drama fix?

I picked up Starz (again) using their black Friday deal, to finally watch The White Princess, and going through their content, I am finding a lot of historical drama and romance. I've watched The White Princess, then there's The White Queen, and The Spanish Princess, and Outlander, and The Serpent Queen .... and so on.

Anyhoo, I was wondering about everyone else's favorite network / streamer. Where have you found the best or most period drama content?
