OK, the most wonderful girls are hard to pick coz there are so many wonderful girls in this game. But how about the ugliest? If i ignore the hard core "feminists" which don't deserve to be in any kind of top lol, I can only find 2. maximum 3, if not really "ugly" at least "not as beautiful" and not as sexy as the others. And they would be in order:
1 - Elena
2 - Heather
3 - Sally (the nerd - Magnar's girl) - but ONLY if i really must name 3 coz only 2 are not enough for a "top"

I can't find more than these, whereby even the first 2 can hardly be called "ugly". And even in that "feminist" class there was that girl with glasses which in fact belongs to the "normal not ugly girls".. And yes, Ari is stupid as hell and has crabs but.. ugly she is not lol.
Did you find more?
