Which is better Paris or Amsterdam?

I have three days to visit one of these cities. I have never been to either of them. I am obsessed with history and architecture. However, the Eiffel tower just looks like a giant triangular chunk of iron to me. I'm not into anything involved with any red light districts. However, I do enjoy a good brew. Also, my brother-in-law is from France and I can't really imagine going out of my way to see more of them (not the most pleasant people from what I understand). And well, the Dutch from what I understand are a tad bit weird. So, any suggestions would be greatly appreciated! And please do correct me if I'm wrong (although I'm pretty sure my opinion of the French is unchangeable). Thank You!
