............................................. I certainly didn't hear "hundreds of variations" so I'd have to say the NI guitars, with their limited sets of patterns, would compare quite favorably especially since you can mix pattern sets in NI using the same guitar. On the other hand, the RT 3182 sounded more human to me, maybe because of the issues I heard?

FWIW: A number of MIDI guitar strum programs have the same or similar capabilities as NI. You can achieve similar results with either BiaB's MIDI tracks and/or converting RTs into MIDI, that is if you have the software to convert polyphonic audio to MIDI. That and choosing a good MIDI guitar sound source can sound great. To make it more human some humanizing and maybe some CCs will work, not to mention that you can easily edit MIDI tracks.
