The first one, and I'll tell you why. The second 
one sounds like it has some great extras in terms 
of sketches and notes. However, the image is a 
little boring to me. It is the facial expression 
of the first cel that grabs my attention. I don't 
really like Gundam Wing all that much, but I do 
know that scene. The awkward action angle and the 
expression on Duo's face make the first cel stand 
out for me.
