The D2 AFCK, being discontinued yet still greatly desired, actually has quite a bit of collectors/resale value. The Chinook, not so much because it's an older model that has been since upgraded with better steel. Not sure if that makes a difference to you or not, like if you're planning on using the knife or collecting/selling it.
In any case, I'd go with the AFCK myself. You can always pick up a Chinook 2 if you still want a knife of that style, but the AFCK will always be harder to get unless they rerelease it.
