Yes, they share the same story, but as far as I know the Wii-Version has a bonus chapter.
The DS-Version had a higher difficulty, but in my oppinion it was a little bit too high. (I finished the Wii-Version, but I wasn't able to finish the DS-Version.)
I am not 100 percent sure, but I think the Wii-Version has 3 different difficulties and the DS-Version had only one. (It's a long time that I played the DS-Version, so I may be wrong.)
I would go with the Wii-Version. (Unless you prefer handheld gaming, because of mobility ...)
