Two considerations about items having been covered by various posts:
1. Body of Korg vs Genos:
I had many Korg worships and actually Korg body construction is definitely better and stronger (that also positively affects look). But it should also considered the weight factor:
Genos 13.0 kg (28 lb, 11 oz)
Pa5X 76. 17,4 Kg (38.4 lb)
2. Construction quality of Korg:
My last Korg, Pa3X, wasn't an example of fully dependable building quality. Even though my arranger was nicely sitting home for 99% of the time, I needed Korg assistance twice for repairs:
-after a few years (after warranty...) various buttons were not working or working not properly (replaced)
-at once one of the output plugs stopped to work, and had to be replaced.
.....nothing is perfect
