I know you can't really compare them because they were so different, Marilyn was all about angel cake beauty while Liz was this dark ravishing vamp, buit who do you like more??
I think Marilyn was more beautiful. She was more photogenic and had better bones and more harmony in her face, while Liz was really beautiful her face wasn't that photogenic, it was rather long, and aside from her eyes, her others features are rather plain if you look at it.
