It depends what you enjoy most about musicals.
YF has spectacular sets, a great cast (currently at least), excellent choreography and a very funny script.
AQ has a simple set, a small cast (some of whom are excellent and some of whom are ok) and a very witty script.
I saw both of them in May and absolutely loved YF. I also enjoyed AQ but YF is the one I would see again if I could. I paid $120 for YF and got center seats 4 rows from the stage.
My AQ ticket was $70 for center 7 rows back. This was too far back I felt for this show.
