I just sold a Tyros 5-76 and purchased a Pa4x-76. Although I didn't own both the Pa4x at the same time I used a Pa3x-61 and the Tyros 5 at the same time. The Korg became my
gigging board of choice. Why? It's great for live play I like where all the controls are within easier reach than the T5 was, plus the Tyros 5 was a little bulkier than I wanted to haul around, but that wasn't the only reason. I liked the sound of the styles on the Pa3x better just personal taste. Audience wise whether I used the T5 or the Pa3x I received a positive reaction. IMO the T5 has some better saxes and trumpets, but I prefer the pianos and organs on the Korg, I used the ensemble feature very little so real loss for me there. I'm still a fan of Yamaha arrangers, got a CVP 307 sitting in the living room..................in a few weeks I'll probably put the Pa3x up for sale................. if I get my asking price at that point I just may consider an s970 or possibly a used s950.


P.S. DonM brings up some very good points, that I just didn't take the time to write in my answer. He's right on the money.
