I actually like the newer hump on the top of the blade. It is very useful for prying.

On the other hand, the thinner handle doesn't give you much leverage and it's not practical for holding much for survival. I find this very frustrating. I own a Model 18 5.5' and it is my least favorite Randall knife. The balance between the handle and blade is way off and the blade feels stubby compared to the handle. A thicker handled Model 17 would be the best of both worlds.
