Okay, first I must qualify this with the fact that I have no experience with either

Other than checking them out on their website and seeing the photos above. But, here are a couple points that might be of help.
In a scandi ground knife, the number 1 predictor of performance is the grind angle. It is pretty common sense that the thinner the grind the more "cutting ability" or apparent sharpness it has, at the sacrifice of durability (everything has a trade off). With that in mind, both knives seem to be ground at approximately the same angle.
IMO, with a given angle, once you go beyond 1/8" thickness, the overall added thickness (read a 5/32" knife) hurts you more than it helps you. Keep in mind that I am also talking exclusively scandi grind here.
So, point number 1 is that I would recommend getting either of which you can get in 1/8" as compared to 5/32". I don't keep up on those knives, so that is up to you : )
Second is that the handle swell is going to "lock" into your hand. The further away from that point that something contacts the blade for cutting, the more apparent force it is going to have (basic physics - force times moment arm). With that in mind, the BCNW seems to have the swell further away from the cutting edge, meaning that I would personally prefer the nordic bear style.
Keeping in mind that I have neither seen nor held either
Good luck with your decision.
