This was a tough choice, but my favourite female sim to play has been Jelly Moulder.

Jelly lives in Strangerville and is the first vampire to join the local army. She has faced a lot of prejudice from her work colleagues and her neighbours (up until recently she was the only vampire living in the town) but worked hard and pushed on regardless. She now has one of the best work records in her platoon. She is optimistic, determined and never lets anything hold her back. Sometimes she jumps into situations without thinking, but learns quickly from her mistakes. Her vampire abilities also come in handy for stealthy undercover investigations, making her a big help in solving the Strangerville mystery.

Though a tough fighter, she has a big heart and a soft spot for cuddly toys. :)
