I bought the ultimate to test against the Disney, Disney sold.
I know the hilt on the Disney looked 'better' but after seeing the film twice I am not so sure its more accurate, his saber hilt looked quite black and white in film.
The ultimate's sound is in a different league from the Disney, it reacts to swipes very well where the Disney just makes a constant growl with next to no swipe noises.
My daughter recognised the ultimate as a much more expensive item without seeing box etc , I think the red coloured blade on Disney makes it look more like a toy. Anyway just an alternative view from the usual 'Disney best' one.
