One is visibly further along in development than the other.
KH3 is only showing you some generic fights. Theres no cut-scenes or voice acting or in-between world system etc.
Though i applaud the return to the world map in World of FF, much like Ni no kuni. I dont know who went and decided that world maps werent good, because they are awesome. They make the worls feel so much bigger without having to make huge landmasses.
