I want to recommend you a cool poll run by : Western 80's Heroines.

It was hard to choose between Jem and She-Ra. However, the former wasn't my favourite character from her series, unlike the latter. So, She-Ra had to win. She was one of my first feminist idols anyway.

For a brief moment I thought I should vote for Cheetara, from "Thundercats." She was a poor man's Shaina, so to speak. I say this because in spite of all the sexism that we see in StS, Shaina still looks stronger than Cheetara. I mean, I'd be intimidated by someone like the Ophiuchus Saint; she comes across as a real threat. Cheetara never caused me the same impression, although she looked like a much respectable woman.
