These are my thoughts as well.
There's of course nothing wrong with seeing more of Bill Murray in his or her sculpt, it's all subjective really and if he or she feels it's the superior sculpt then that's all that should matter because it's their collection. Opinion duly noted, but like you said, they shouldn't expect everyone else to agree with their opinion. However, if he or she genuinely feels their sculpt is superior, then why are they seemingly attempting to convince the rest of us that it's the superior sculpt by crapping on the BW one and suggesting that anyone who doesn't agree that their custom sculpt is superior doesn't know what Bill Murray looks like?
Sounds more like a case of attempting to convince themselves that their custom is the "superior" sculpt by hoping that everyone here would agree because they probably paid a lot of money for it. When that fails, then just resort to telling everyone here that they don't know what Bill Murray looks like.
I attempted to be diplomatic in the way I initially disagreed, but it seems like they want to go the route of suggesting that we all don't know what Bill Murray looks like when they didn't get the answer they wanted.
