I'm a Yamaha guy. I own a Tyros 3 and a Motif XF6. After several years with the T3 I have found that I love the acoustic voices particularly the SA and SA2 voices but I think the overall sound of the T3 is too refined, especially drums. The Motif on the otherhand is bold, live and exciting. So I use the T3 only for it's voices and not it's styles. Once you hear the difference with the Motif there is no going back. In this comparison I hear the same thing. The Korg is so much more livelier, especially the drums. At first I thought it was a Reverb difference (more on the Korg and less on the Yamaha) but it is more than that. I thought the Korg won every comparison except maybe for piano. However if there were any SA2 voices on the 950 they would have been better than the Korg version.
