Face- the least disputable best looking musume is Ishikawa.
You do not have to know her personality to consider her good-looking. in fact she is the only musume i thought good-looking when i first saw a picture of MM.
More interesting and controversial faces are Goto (Rika would hardly pull off androgyny) or Yaguchi (post surgery. looks old, artificial, arresting) or even Tanaka.
'CGed completion' better describes Abe or Matsuura or even Ogawa, if you time your once upon right.
also, Rika's facial shape/ structure probably means she would not look too marvelous bald. this is
very important. I suspect Takahashi might look rather good bald. So too Goto.
Kago is the cutest. especially from The Peace onwards.
body- Supermodels rule. the closest would probably be Kaori then.
Unbiased two-top: Ishikawa, Abe
