While I like the D'stance, the neck is too long (it really spoils fighter for me). That would be the ONE area where the Yamato is superior (although I believe there are more, but that's my opinion)
You are right that the legs are more muscular on the D'stance Overall I still like Yamato's interpretation better.
It's a shame that you are still looking for the perfect YF-21 (which I found with the 1/60 YF-21) as I'm still looking for the perfect VF-1!!!
