The VSL stuff is in a class by itself. I walked into the VSL booth at NAMM one year, intending to just take a shortcut through it, and was totally captivated by what was playing over their sound system. I had to sit down, totally forgetting about where I was previously headed, and just soak up that fantastic sound.
Not to be confused with the VSL libraries that come bundled with Kontakt. Those must be VSL's throwaway first attempts, because they're not in the same league.
Not cheap, but a reasonable compromise between price and expressiveness is EWQLSO. Takes a dongle, though, if that's a showstopper for you. The first-place winner in our orchestral shootout was an EWQLSO Gold entry.
GPO is an excellent budget solution, especially if you're doing orchestration for pop/rock rather than orchestral music per se. Randy Bowser has made some very good recordings with it.
When we did the orchestral shootout, the main lesson learned was that the skill of the operator is
far more important than the quality of the library. We had some great entries from talented orchestrators using very modest tools, including the much-maligned TTS-1.
