I voted for men. I know from experience such as, "Grandpa, I can't open this jar. D: Can you open it for me? ... Thanks!"
It's just a fact of nature that ordinarily men are physically stronger than women, due to naturally being built that way.
But, like I said, that's "ordinarily." A female who works out regularly and is in the peak of her physical condition is gonna be stronger than some scrawny little dude who sits on the couch all day. A female bodybuilder would be stronger than the average male. So it can vary.
BUT WE KNOW THIS ALL ALREADY, DON'T WE? <3
