Which one of Henry VIIIs wives had it the best?

Anne of Cleves wins that title hands down. Henry was appalled wh en Anne waser aside brought to England and believe he'd been deceived about her appearance. Thus, he set her aside. Anne willingly consented to the divorce, as long as it meant she could remain in England and would be provided with a home. Henry ended up treating his estranged fourth wife like a sister, and it was a win/win situation for them both.
