To me the two are completely incomparable. Here's a prime example:
I love both figures a lot. In fact vintage Fett is my favorite figure from that line, but he's by no means comparable to a counterpart that came some 28 years after, nor visa versa. Two separte eras, two separate lines. You can't blame the oiginals for there sculpting "imperfections", in the 80s they were the sh!t.
It's a pretty even split with this as far as love vs. hate. In the end it'l be "agree to disagree" which what I've settled upon.
