Relative to the price, pretty comparable (of course these are my subjective opinions):
Fit/Last: this is subjective so AS = C&J
Uppers: AS < C&J; advantage to C&J is the leather uppers for their dark brown (I think they use that 'untreated' leather; don't know what it's called)
Colors: AS > C&J
Sole details: AS > C&J
Sole longevity: AS > C&J
Accessories (e.g., dust bags: AS = C&J
Sock liner: AS < C&J (C&J uses a full liner; however, to me this is a minor detail)
Styes: AS = C&J (again, this is pretty subjective)
Can't comment on other construction materials (toe puffs, counter, etc.) since I have never deconstructed my shoes. Personally I think the quality vs. price is fair. C&J HG is slightly higher than AS Ex but maybe that should be expected.
FYI I recently picked up the cherry Moore.
