For me it’s Valentine and I think that has something to do with the progression of the story. The gang is camped by Valentine in the beginning when everything is going well and everyone is happy. Valentine reminds me of that time in the gang where everyone is thriving. Saint Denis is a beautiful and very different city but it also gives me very different vibes. Especially in the end when the camps at Annesburg. Annesburg is probably the city that I dislike the most because it makes me think of the end of Arthurs story and how the gang is turning againts each other.
