floor: which one do you adore?

Over the past few months I've been noticing flooring of homes more and more. Maybe it's because my aunt is in the middle of a re-model or possibly because another friend is debating if she should paint her floors white. I'm personally a sucker for old herringbone floors (number 5) or a wider and darker wood floor (number 1) but when it comes down to it, it completely depends on your aesthetic and what you love.

What would you prefer? Herringbone? Dark hardwood planks? Light hardwood? White painted floors? Cement? Chime in!
