I like them both equally, they just completely different genres like the OP said.
JRPG's are for more about watching the story, the development of characters, they mainly are linear without much choice, more like a movie in my opinion. But i've played great JRPG's this gen like TWEWY or lost odyssey, i think we just have to wait for more good ones to release (especially in PAL region)
WRPG's are like Dungeons and Dragons, you're the character, you usually have impact on the world around you, characters and the good ones tend to be non linear. Offering loads of choices and replayability, the enable you to create the story. And Fallout 3 is amazing at doing so, i should be able to play mass effect finally around summer when i get time.
In the past i prefered WRPG's but now i got older and i appreciate them equally.
