Pahlavi was better even though that isn't saying much.
I've done a lot of research on women in Iran, and Khomeini is one of the worst things that ever happened to them. He was pretty much a monster.
Indeed - Pahlavi's support for and provision of Women's Rights is one of the reasons as to why so many uneducated and delusional folk joined the Islamic Revolution. The Pahlavi dynasty provided for, inter alia, the expansion of the electoral law to provide for full universal suffrage and widespread educational opportunities were implemented for women (not to forget the abolition of the veil).
