I dont know too much before, like I said, but I am in the military, and the kinds of service dogs the military are looking for have to be high drive....you need an animal who not only enjoys the searching but also wont give up. I am medical service corps....dogs that have a high drive and are willing to look for people for as long as possible save lives. I am hoping to train my puppy for rescue missions along that line...I think the military could sorely use a search and rescue dog with each ambulance platoon. but again, high drive = very important...
And on a second note....for christ sakes...they're all the same...the same internal workings, the same structure...some dogs will always be more high drive than others...some will be more lazy...you will see that in both WGSD and GSD. One of my Captains worked with and bred german shepherds, and his direct quote was, 'I've worked with everything but a pure black, and its pretty much ding, they're all the same.' so you can breed high drive and temperment into pretty much any animal...alot of that is dependant on the breeder....it just so happens that most of the people I know who I have mentioned the high drive/intelligence....it may just be that they are all doing something right.
Pretty much this comes down to truth and fact, we all have our own truths - what we believe is real, and then there is the fact....what we know is real....our truth is that the WGSD is awsome, yours is that it is not so much....the actual facts....we dont know for sure because there has never been any hard data or testing in a controlled situation. I actually looked for something in the Virginia Tech Journal Database...the entire database...and I could find nothing. Until there is resaearch done like that, they are all the same I guess. (mmm, that might be a good graduate thesis paper though)
