They're both good knives. I like 1095 better than 440A, but Kabar's heat treat of 440A results in a tough corrosion resistant steel that takes/holds a decent edge.
The Next Gen feels stouter in my hand than the traditional Marine style does for some reason. I think the overall design of the Next Gen results in a better using knife myself.
I'm still waiting for a Next Gen handle with a 1095 blade. It would be the best of both worlds.
If you're not dead set on the military style blade, the Becker BK7 or the Kabar Potbelly offer 7" blades of 1095 better suited to camping/outdoor use. I have the Potbelly and it's a beast of a blade. I've never had ANY 7" blade that chops like it does, yet it will carve fuzz sticks almost as good as my Mora's.
