Natalie Portman or Rachel Bilson?

Natalie Portman or Rachel Bilson? Which one as the best movies and which one is much prettier.

I think natalie portman looks prettier, but her acting sucked in star wars

Natalie Portman has been in more movies than Rachel so I think Natalie has the best movies.

Her acting is pretty good. Anyway, she was in E's 25 Most Stylish and Rachel Bilson wasn't.
