Based strictly on pedigree, without knowing the dogs or the dam who will be used (and both should be HUGE factors in selection) I would go with dog #1.
The Talka Marda dogs, including several of Jarek's littermates, have been hugely successful both in their own performance and their ability to produce excellent working prospects. That right there speaks to the quality of the dogs and bloodlines, particularly when it is seen consistently across several individuals, not just one dog.
Dog #2 has been successful in his own right on the performance field. And I do really like much of his pedigree. I have owned several dogs closely related to him, and currently own 2 offspring of his maternal grandsire, Ernst, and a granddaughter of his paternal great-grandsire, Pike. These are some of my favorite bloodlines. However the pedigree to me is unbalanced, and while I love many of these bloodlines I wouldn't care to see them combined together this way or this closely.
Of course, more knowledge about this dog, his own siblings, and what he's produced in previous litters may prove me wrong on that. But since I don't have that info (especially compared to the notariety of Dog #1's immediate family), I'm basing this just on the pedigree alone.
