I don't think there's any contest. Bill Gates built Microsoft, Ballmer is overseeing its decline. Steve Jobs has built the #1 design and marketing company; love Apple or hate them, they are producing what consumers lust to own.
My admiration is for Google. Their sheer vision is awesome, take Street View. What other company would spend countless millions developing a product that is then available to everyone for free? OK, yes they spy on us. But at least they don't want us to keep paying them, and I like that business model.
