I am no expert either, but have owned the chinook, and handled the yojimbo as well as the kerambit. I understand that the wharncliff (sp) blade is good for deep slashes due to the edge all the way forward creating a deeper cut in the same distance compared to, say, a chinook. I would think the difference would be only a 1/4 inch or less, but that may mean hitting the artery that ends the confrontation. The yojimbos blade has a very thin tip so it could get damaged easily depending on what you're doing with it. The best part of the yojimbo, to me, is the handle. It offers a quite secure grip. Havn't spent too much time with a compression lock, but have only heard good things.
With that said, the chinook has what is probably one of the strongest lock backs ever. It also has a handle that would be near impossible to slip off of if you've got a good grip. The blade is tilted forward slightly aidding in cut depth. The blade is also thick yet very pointy. -In a generic stabbing motion, to me, the arm extends, then begins to cross. This is where an aggressive clip point blade is best. This could be done with the yojimbo, but to less effect. This could not be done with the kerambit. In my opinion, to sum it up, the kerambit is a pure slasher, the yojimbo a good slasher -that can be used to stab, and the chinook, a great "slasher", "stabber" combination.
Please keep in mind that the farthest my trainning extends is to a few dvds. But I try to think logically. I'm sure the yojimbo could be used quite effectivly if that's what you end up with.
