Actually I wanted to get the Garritan Auth Steinway, however some users find that the steinway in QLP have even more depth. Moreover, there's 4 flavours in the QLP so yah haha i guess it's better value for money.
Might be getting the Garritan standard version if the steinway on QLP is not that great, I was mainly looking for a bosendorfer and yamaha. But Ivory's bosendorfer is ridiculous so finally decided to go with QLP.
Maybe you should get the Garritan Steinway and share with us how it's like!
