Thanks for clarifying. I think there are better ways to ask a question like that (eg. "what differentiates x from y.."). It's also built on an assumption: looking at those two sites side by side, there's nothing glaringly obvious that one is "much better designed" than the other.

One thing I try to remember is that this site is probably something someone loves and takes pride in. It's fine to offer a critique and constructive crits, but I try to remember that a sharp comment like that (without much seemingly obvious interest in an answer) can be super tough for the designer.
