I agree with the OP that the three knives he is looking at are very good ones. I also like the Buck Vanguard Alasksn Guide series. Here's the description:
Sporting a 4-1/8" drop-point crafted of strong S30V steel, the Vanguard has a rosewood handle and a polished brass butt and guard. Available in a rubber-handle Vanguard version with Cordura® nylon sheath. Developed by Crucible Steel, S30V is made up of metallic powders fused together under intense pressure and heat. It is tempered under extremely high temperatures then cooled in a cryogenic freezer. The resulting metal delivers a fine combination of edge retention (45% greater than 420HC), flexibility and hardness (59-61 Rockwell) while remaining easy to sharpen with conventional stones. This steel also has a high chromium content for oxidation resistance. For even greater corrosion resistance, each knife is treated with a titanium aluminum nitride coating. Our field testing and independent Cutlery Allied Trade Research Association tests prove these knives outperform those crafted with other blade metals. It also has a leather sheath. Made in USA.
Overall length: 8-1/2".
Weight: 6.3 oz.

I also highly recommend the RAT RC-4. If I could only own one knife, this would be it.
