GPO seems to fit the bill a lot better with modern music, Pop, Rock, Country, Hip-Hop, etc. In my use of Miroslav it exceeds in ballads and quasi-classical music. I am glad to have both in my arsenal and they both see action quite a bit. I never really felt, judging from the demos, that the other libraries out there were worth the amount of money they ask for. As someone who does his own sampling from time to time, I do understand the time and cost involved to do something the size of an orchestra. I don't begrudge them any at all about that. It's just that in most music we listen now doesn't really have need for any other articulations than you get in a smaller, less expensive library. I may take a shot one day at paying for a membership to try one of their competetors out but for right now I'm pretty happy with GPO, Miroslav 2, and LSO.
