A random JP comment caught my eye. Interesting. It strengthens my opinion that a typical guy would naturally like the concept of Tifa more.

ティファは男の理想の女性で、エアリスは女性の理想の女性なんじゃないかと思う
Tifa is a man's ideal woman, Aerith is the woman's ideal woman

There are, of course, exceptions to both. It's just an interesting general statement someone made, lol.
