One was made in japan and the other was made in taiwan. Japan being further up north and futher east.
One was made by people who don't speak japanese, the other by people who don't speak chinese.
One had to be flown from japan to where it is now, the other from taiwan.
One has more japanese sweat on the pcb than the other.
Luckily the other has more taiwanese sweat on it to make up for it.
I could go on, but it really would be easier to do a search on what the specific differences you want to know about.
Like if one was slightly less orange than the other.
