Hi! I'm also trying to choose between moonraker and atlas, but I think because I'm going to be located at Guy's campus and it's going to be my first year of uni, I am going to choose Moonraker just because its around a 15 min walk from Guy's I believe and also it seems more student-ish. Also, I'm going to be new to London, so I feel like being closer to campus will just be easier. Hope this helps
