I disagree. Ashlee Vance spends quite a bit of time talking about how the SpaceX approach differs in his biography of Elon Musk. Basically, Musk turns out to be manically cost aware, and a lot of what SpaceX does is focused specifically on that. One of the examples given are that they figured out how to use stock electronics rather than the very expensive radiation hardened versions that are conventionally used, for a 10:1 cost saving. They've done this throughout their entire system. I'd be very surprised if ULA were able to match.
