Just finished listening to the entire comparison. Both keyboards sound fantastic - no doubt about it! My take on them:
Pianos - both about the same for the Grand Pianos, maybe a bit more depth to the Yamaha, though.
Guitars - Definitely Yamaha gets the edge here.
Organs - Korg has some really neat effects.
Brass - Yamaha gets the nod here - great brass.
Stings - About equal, IMO.
Drums - Yamaha by a mile. Much hotter, far more realistic, crisper, full sounding.
Don, get the T5!
