I think it may just be what we were "brought up with" as far as preference. I personally prefer the BBQ sauce over the dry but will eat both equally. The dry is IMHO sometimes TOO dry and to me like eating smoke flavored sawdust. In my mind BBQ means sauce while smoked means dry rub. Though both are referred to as BBQ, I have to agree w/Countryboy... they really are two different things. 
Those shoulders (and ribs) look good enough to EAT Mike!
