I do see where you're driving at. I guess it just comes down to personal preference. Somehow Ayla radiated youth and beauty -- she was tall and statuesque, you know? Melissa's pleasant-looking for me at best, and I don't always agree with her um, choice of clothes.
But I totally agree with your last sentence there.
One random thing: I loved Mario too!! But his behavior after leaving the show seemed totally immature, so I'm no longer a fan. ^_^
