After School "Ah" or "Diva"??

Would u prefer After School with their latest single "Diva" where they added 1 new member named Uee?

or would u prefer After School with their debut single "Ah"? where they stil have 5 members excluding Uee? comments pls! for me,i personally like "Ah" becoz of their singing style and dressing style but recently "Diva" has started to catch my attention too and the song is really catchy. these girls are the Korean version of Pussycat Dolls
