I think the 7 or so inch blade bowie style knives are probably the best all around wilderness/camping knives. Just long enought for chopping fairly efficently, but can still use them for skinning and gutting etc. Easier to carry than the longer choppers too.

Of the bowies I have and have used I think the regulator wins in most comparisons. I plan on carrying it for most of my backpacking/wilderness/hunting adventures. The only time I would take something else is when I'm planning on being in a very wet environment like multi day kayaking trips. Probably take my stainless SEAL 2000 for that.
