Love these styles... Stylewise it beats the standard Tyros 5 styles... 
I have to agree not to mention the KORG is much better suited for a pro live performer also so many kool features .. 
Both have strengths..
Dont forget about the Tyros 5 pro features..
-Ensemble voices
-Organs a step beyound just the B3
-More (memmory) and better expansions
-The vast user libraries with styles
Both are awesome arrangers, and PA4x definately has some great strengths, I also love my Kronos..  
Wish Kronos, would combine the Kronos and pa4x into a stagepiano.  Its still beyound me, why these pro Kronos players still cant see the usefullness of arranger styles..
