Well, I think if you're wanting to compare all around drum mixing tools then the Abby Road collection is probably not the one you want to look at. Those have more specific uses... studio drummer is probably Native Instrument's equivalent to AD 2. Both are good, I just have a bias towards NI because of their accessibility efforts. lol That, and the Abby Road plugins caught my ear much more than AD 2 did. That vintage dry was definitely good, though.
