It's an interesting dynamic.
I feel like when you're on the Throuple path, Maya gets the better moments, you get the kiss in the swimming pool, you get the classroom scene, when you have to choose a hangout during Chapter 7 (I think), she gets the TV and (imo) the better sex scene and you get the Halloween couch scene. Even if you go with her when they change in the Ep10 flashback, it feels more substantial. Maya grows in confidence and explores her sexuality more. That's not to say Josy doesn't get her moments, the gym scene is fucking great, Josy's prep party scene is incredibly passionate and intimate, but the dialogue for Maya is better (and i feel like it just feels right to see Maya knowing her father siutation, The Josy kiss at the Dorm Party is one of the most romantic moments in the game, but I feel like Maya's moments shine more.
When you're off the path, I feel like Josy gets the better of it, her hangout if you didn't break off the throuple is better than Maya's, you get the chance to kiss her at the HOT party and the barbeque, Maya's scenes are a lot more forgettable if you aren't off the path.
The Maya scene if you break off the throuple is one of my favourites in the game though
