GSP, I have owned golden retrievers, labs, spaniels, german shepherds, all sorts of dogs and by far without a doubt in my mind the shorthair is the smartest dog compared to all other breeds I have owned. Plus for in the house- they are great guard dogs, great with kids, very affectionate plus they are "short haired" not as much mess in the house, they still shed but it is much easier to stay on top of and when in the field I don't have to spend a half hour brushing the chiggers and junk out of their coat. A couple pets on the head for showing up the pudelpointer they were running with in the bird field and they are ready for the truck or couch. (that last line was for you Mustad for not giving any mention to the GSP for pointing)
