Well, you listed fixed blades..so I'll assume that's what you're interested in. That's what I'd go for.. A folder wouldn't really make a whole lot of sense in a camping scenario.
You have many options. It depends on your budget. You listed some of the higher end knives available, so I'll assume you're in the 100-150 range which is pretty much the bread and butter of high end knives. You'll find some semi-custom work like Bark River as well as some mass produced stuff like Fallkniven. Both would treat you extremely well.
Most people find that a 4" blade is all you really need. Personally.. I like a little longer so I can "whack" stuff. You can do that with a shorter blade, but when you get into 6-8" it's MUCH more efficient.
My ideal knife would probably be the Fallkniven A1 and if the A2 weren't priced so high..I might go with it. The A1 is a 6.3" blade. Pretty nice blade geometry (they call it a modified spear point..i wouldn't necessarily argue, but it's more of a drop point). The Fallkniven is also what I'd consider a "high end" knife. There are some customs that would rival and/or exceed it's performance, but the price isn't worth what you get in my opinion.
If you find yourself thinking a 4" blade would be sufficient.. Check out the Bark River Bravo 1. It's gotten wonderful reviews since the day it was made. It's a a great knife. Bark River also makes some larger blades (Rogue Bowie which is a beast, big sky camp, and canadian camp...to name a few).
But for the sake of argument..this is what I'd buy in length ranges.
4"= Bark River, Bravo 1
6"=Fallkniven, A1
7"= Ranger, RD-7
If you want to go larger than that..You're getting into machete/khukri/golok territory. Bark River makes a nice Golok (about 200 bucks, but it's a beast)..but for the money I'd get a simple Ontario Heavy Duty Machete. You can get one of those for like 25 bucks.
This isn't to say that you couldn't get a simple KaBar camp knife and be perfectly happy with it. You just might. It all depends on what you want to get out of it. You listed higher end knives..so that's what I suggested. If you want to go cheaper..check out the Ontario Spec Plus line. They're cheap, but pretty good. They have a Marine Raider Bowie that's fairly large and would make a great brush beater.
Oh, and blade steel.. The only steels I would concern yourself with if you're a new person are: the 10xx series (1095/1085), 5160 (only if you want to get a ranger knife [brand]), A2 (if you want to buy a bark river), and VG-10 (if you want to buy a fallkniven).
The basic rule of thumb is that a good carbon steel like: 1095/5160/A2 will perform better and hold it's edge longer than a good stainless: VG-10. Stainless has the added elements like Chromium that add in stain resistance. Which means it'll prevent the blade from oxodizing in things like blood and/or water..things like that. It WILL still rust. It just needs less maintenance. If you buy from a good, reputable, company.. Ranger, Bark River, Fallkniven, etc. You'll be less likely to have to worry about your blade tarnishing, but that's not to say it won't happen. A little bit of food grade mineral oil (laxative) goes a long way. It's not toxic to you and will keep your knife in good shape.
A lot of information, I know. It's just the basic rundown. Good luck.
