Hi. I have a pa500 and a Psr1500 (the previous model to the s700). 90% of Korg sounds are very good. Only sweet, cool, live and Mega sounds are worth in Yamaha, Xg sounds are very bad. If you want a very good controller take the Pa500 (not good key feel though). If you want plenty of styles take the Yamaha.
