WP8 or BB10?

I'm going around the forums and asking the readers which one they think will succeed in the marketplace. As far as I'm concerned there is room for 3 ecosystems and I think WP8 will beat out BB10. Maybe you don't think there's room for 3 ecosystems. Or maybe you think there's room for all of them. All of those, valid answers. I don't care what your opinion of either company is, I would just like to know which one you think will be successful in the marketplace.
