Never handled any of the knives you listed. I would guess, though, that any of them would be quite serviceable. The Becker might qualify as the "best buy." I have two Beckers, and rate them highly, for the money. My idea of a "do it all" survival blade, though, is something a little smaller, maybe in the 4 1/2 - 6 1/2" category. Personally, I favor the Busse Badger Attack for the "one knife" does it all scenario. I also think the Fallkniven A1 falls in there, although I'm not a fan of "rubber" handled knives. It's just a personal prejudice I have. The Becker Companion comes close but the tip is a little too blunt for real fine work although it would probably be serviceable. But give me a small folder, SAK, or multitool and a Companion and I can do it all. You don't absolutely need a big knife for chopping. They are wonderful, as is a hatchet, but the thick spine of the Badger, Companion and A1 will allow you to hammer on the spine so that you can easily chop with these knives. If you are talking really long terms survival, give me an axe any day.
Some guys like tantos (like the Anaconda you pointed out). The idea here is that given the tanto point, you can choke up on the blade and use it for fine work. There is good logic in this, I think. I'm just not a tanto fan but I think I have to get me one some time and try it out. However, the tip on my Fallkniven A1 is fine enough to slice newspaper articles out of the paper so you don't really need a tanto point for doing fine work like cleaning a 6" trout. A reasonable distal taper on a drop point or clip point should get the job done.
However, if big knives are what you want, then a couple more to add to your list are the Busse Battle Mistress and the SteelHeart. And I would also add the Natural Outlaw. The really nice thing about Busse in general is the Infi steel. This has to be one of the most highly regarded carbon steels on the market.
Oh ya, I doubt you could go wrong with a Chris Reeve one piece. His knives are high on my wish list. And A2 is an outstanding steel. My Badger Attack is an older Busse that was made with A2 steel and I really love it. Takes one hell of a razor edge, easy to sharpen, and tough.
I forgot to mention that Jeff Randall has a new "survival" blade out (made of 1095, like the Anaconda) that looks nice. I wonder if anyone on the forums here has tried it out yet. It's another knive on my want list.

I get some pleasure from finding a relentlessly peaceful use for a combative looking knife.
