Basically they are the best most accurate. They also came last so they are improved versions over the cc. The py just isn't accurate enough for me. Very well made kit but not quite accurate.
No offense to anyone but....
Accurate to WHAT?
A Hero? Ok..well, its PYRO. Hence the name.
I love what Julien did with the Pyro, basically reworked it to look like the hero. To me, that looks the most "accurate" of anything out there.
CC, V2,3,4 whatever, are all scratch builds of someone's interpretation of what the XWING SHOULD look like. Yet they get deemed more accurate than someone that actually was cast FROM a production used piece. Cleaner? Shaper? Sure. More accurate or authentic? Not so much.
If you Look at a film used ship, they are "pretty rough". Im always amused when people complain the Pyro is "Pretty rough" and therefore less authentic.
I guess "accuracy" is in the eye of the beholder.
Bottom line, Pick the model that best fits what YOU think looks right.
The only eye that counts for YOUR collection, is your own.
