I can't find anything concrete, but I think it's fair to say that the attach rates for the 360 and PS3 are similar, and as you say, Microsoft is only narrowly 2nd out of 3rd in terms of consoles sold. I think a case can be made for the 360 being more valuable than the PS3, though, just because of the online service offered by Microsoft. They had at least 20 million users paying for gold in January of 2012, which comes to around a billion dollars a year for Microsoft. Who knows what the operating costs are, but I'm sure they're doing well, especially considering that they show advertisements on top of the subscription revenue. I can't find any numbers for PS+, but I'd be shocked if it's anything comparable to what Microsoft has going.
