Hmm... I think I prefer the Jarosz handle for regular knife use, basically everything leading up to wood processing. However, sense that can be a use of a survival knife, I think a BK7 would be the way to go, of the two. I voted BK7 but it's pretty darn close, IMO.
I prefer my ratweiler, so I don't have extensive experience with the two knives mentioned but I did have the smaller globetrotter and still have a BK4 which have very similar handles of the knives mentioned. I think it comes to personal preferences but both would serve the purpose of a hard use, one-knife option, if you must only have one knife I guess. Maybe get the one that's cheaper or get a used one to save some coin. Whichever comes up on the exchange first.
To muddy the waters a little more, I like the esee 6 for such a use. It comes with a nice sheath and a more useful blade design than the above two, even if simply for the lack of a swedge if you desire batonning wood.
