My only problem with Shiloh's is that they're essentially dumbed down over-sized, GSD's. They softened the true GSD temperament and drives, that makes them such versatile dogs and when you breed for one aspect, whether size, conformation, or drives, you lose proper temperament and you get unstable dogs.

Plenty of GSDs have good bone, just looking at the German show and working lines(particularly the DDR and Czech working line dogs). The dog I posted the picture of is a Czech lined dog, with a few DDR dogs in his pedigree.
Here's a picture of a DDR Great Dargo von den Thuringer Kronjuwelen.
