Aesthetically, I'd take the tourbillon. But only, because I don't like Roman numerals. Technically, I'd take the micro-rotor, because I don't like Tourbillons and the micro-rotor movement is exceptionnel. This probably won't help you, because it's just my taste ;-)
But I do have a (slight) preference for the platinum with enamel dial. Like the even cleaner and sharper look of it, and enamel dials are simply gorgeous
