They feel better.

My wife doesn't do well with any female contraceptives, and so instead of making her suffer, I wear condoms. I have no fear of STI's, so that detractor is out. If both stop pregnancy, I'm going to go with the one that feels better.

Or in my case, the one I can afford, so I still use latex. But, if I could afford it, I'd switch.
