overall sound(except for Ac piano and some saxes)Korg sound better(mainly better drums and bass).PA has more "pro" look than PSR.

styles arranging,realtime countrol,SMF and seq ease Yam's better.

though Korg has good ballads and some 16s ,bossa's Yam's overall styles are more usuable.
but don't forget in Korg you can replace all styles.

seq and sound editing-Korg is better.

but Yam has these major advantages.

Vocal Harmony with compressor,EQ and reverb

SM card input and USB to device input(play thousands of SMFs and styles with ease)

music finder

realtime pads(can play loops-you can't in KORG)

better and more fills

factory styles more tuned toward 4/4 most popular music(in KORG B section starts from over orchestrated ethnic and latin styles are virtually unusuable).

and ofcourse you can't beat YAM's 3rd party support and free styles.

basically if you play arranger music-yam is the choice.

if you do more studio and live with occational arranger work-PA.
