I really like a pretty girl with tear filled eyes that eventually overflow. The first tear is a climax, or peak moment. Anyways, I prefer big enough tears to be visible, rolling slowly down the middle of the cheeks.
I love seeing more than one path of tears streaking the face. If left unchecked, it is a plus.

I also like seeing a tear stained face when the crying subsides.
As those who have read other of my posts know, I love wiping tears from the other person's face, and if she is close to me ( wife, close friend), I also kiss the tears from their face.
