Setting:
Jrpgs. More imaginative and absorbing. Wrpgs are so predictable, Japan has its twist on things. Even when it come to characters, in wrpgs they usually scan real people into the game and call it a day.
Music
With the works of Yoko Shimomura and Nobuo Uematsu.. They are not on the league honestly. Jrpgs all the way.
Usually Wrpgs. Many Jrpgs franchises have never evolved in a long time.
Combat
Usually Jrpgs. This an area where Wrpgs need to step it up. In games like Skyrim or Dragon age the best thing to do is to use the strongest skill available. It requires no management, no planning, almost nothing really.
Story
Jrpgs, usually they try to tell something meaningful, not just a series of events that take place. Characters also usually have more depth to them. The extreme twists on the characters design is not usually preferable though.
