Agreed. And there are several other chilies that are worthwhile as well. I use chipotle for grilling - when the time on the grill will be too short for the food to take on much in the way of smoke (I use smoked paprika as well, in the same way, when I am looking for smoke flavor but no heat).
Me, I never use paprika in rubs for barbecue at all. Imo, it does not stand up to long dry cooking at all. Its rather subtle flavor craps out early and it becomes bitter.
I only rarely use cayenne for the reason stated upthread. Heat, yes, but no flavor. There are too many chilies with both so I choose one of them or, usually, a combination. See
here.
For decreasing heat but increasing flavor try a flavorful chile - like ancho or pasilla.
