I have never been particularly a fan of the "marine corps" bayonet/utility knife although I have always generally liked the shape. The blood groove turns me off. I guess if you are in a fox hole, need to dig or pry out rocks (better than bare hands), and have nothing else, it works and it is an okay fighting knife. So, from that point of view it's a "good survival knife". Probably make a good ginseng knife and the kind of knife I would choose for such tasks.
Fallkniven are a step up in the blade department. I have a F1 and it is a good knife and really all you need for a general purpose outdoor "survival" knife. But many prefer something with a longer blade. Hence, the A1 is a good choice. But do I really want to dig with it out in the woods? Probably not, if I had any other options. So it depends on your typical usage and I would have some other tools with you.
I would choose the Fallkniven if I could afford it over the Kabar marine's knife unless you really intend to abuse the knife.
Other choices... Kabar Becker BK-2, BK-10, BK-7, BK-9, or the general purpose 4" BK-16 or BK-17. I suspect since you are considering the marine knife, that the BK-2 or BK-10 wouild appeal to you. The BK-7 is larger and probably a bit better chopper for camp odds and ends and the BK-9 is a better chopper than the BK-7. Again, I hope you have a saw or hatchet with you, and a smaller knife (perhaps a folder) for finer or more detailed cutting tasks. I recommend the Becker knives often depending on the use.
The ESEE knives are good.
Other knives I like a lot.....Blackjack Classic 125 for a woods knife. It will do everything a knife is supposed to do short of chopping. They also make the Halo and 1-7 which many like if they have used one. These are made by Bark River for Blackjack. Many of the Bark River knives would be a good choice. Added: But these exceed the $100 limit.
