I am a long time SC veteran. Because of this post I tried an MA for the first time. Wow!
One thing that I found annoying about SCs over the years is you spend so much time waiting around for the girl you want, while politely declining all the girls you don't. It is hit and miss when your fav is working, and she can end up at somebody else's table or in the CR without you. With an MA, you book the girl you want and you get her all to yourself. In fact, they seem to go out of their way to make sure you don't see any other men at all.
