I prefer the Korg over the Tyros. Yes the Korg does have that "live band" feel. I feel Yamaha's styles are over quantized. I think that in turn makes them sound less natural. It's not to say the Tyros styles are bad, but for a more natural feel I prefer the Korg. (If I had another choice I'd say Ketron)
