I do have garritan world instruments, sadly some of the patches have a fair bit of noise in them. On the whole I found them quite lifeless, but this is comparing against libraries several times more in cost running in kontakt, engine etc.
I also have some of Eduardo's libraries (epic world, forest kingdom and others) and that's a good place to put money down for world instruments IMHO, among others. If you go over to vi-control.net, sometimes there are ppl selling these libs used.
Play works fine for me, but I don't use it as EWQLSO is not a good match for what I write atm.
