Maybe Emma is a little stronger. But a catfight is not a test of strenght.
Probably Kristen would be more vicious in a fight, so it woul be very close and not one side.
I saw pics of both girls training with gloves for her films, so they have a basic skills too.
They have a lot of ego so win would be the unique option for both beauties.
So probaly it would be wild and long.
They rivalry is very exciting to all catfight's fans, but look at the evolución of the polls.
Some years ago, Emma won easily, she had a big advantage in fans and votes.
But now it's close and Kristen win sometimes, especially because she looks more sexy and confident than before and because Emma still play the rol of "good girl" all the time, so it's a classic devil vs angel fight.
For me, it's the best freud ever in Hollywood and I totally love to read the stories and vote in the polls, many thanks to the authors.
