I had a similar decision to make about 8 months ago. I was basically choosing from the Becker BK9 and the Kabar 1211. In the end, what swung the vote was the the Kabar would come with a Kydex sheath, instead of the nylon one of the Becker (I don't like nylon).
I think in retrospect, I would've gotten the BK9. Don't get me wrong, I really like the kabar. The only place it was lacking was weight and length. With a longer blade and an overall heavier weight, it would've likely been a better chopper. When I was gathering firewood and hacking some of the 1 inch-ish diameter branches off of my wood, it took more effort than I would've liked. My pack was around 40lbs, and a few ounces wouldn't have weighed me down significantly.
