I do hope you know that ALL steels are just compromises made with different concessions for different applications.
1095 is a standard cutlery steel. It is not as "springy" as 5160, but that same trait allows 1095 a better, sharper edge according to most accounts I have read.
So, I would think of 5160 as better in a chopper and 1095 as better for a cutter. Mileage may vary, especially with heat treating differences.
0170-6 is like "product improved 1095," with the addition of some other elements, most notably vanadium. I view this one as splitting the difference, properties-wise between 1095 and 5160 for the purposes of this discussion.
0170-6 is like 1095 but "more." It is probably more impact resistant than the simpler steel, but not a notable on that front as is 5160 spring steel.
Personally, I'd rule out Beckers for the moment. They might have a "lifetime" warranty, but the life expectancy of Camillus isn't looking too hot at this time.
In 7" or less I am a fan of 1095. Anything larger should probably be made of something else. I am really becoming a fan of Ontario's RAT line in 1095. The RAT-5 I own has been a really great performer and came in at about $80.00
I own knives that are far more expensive than the RAT-5, but none of them are more handy or feel better in my hand. Those Rangers are bruisers by comparison, so you really need to take stock of how you actually use your knives in the outdoors because the three candidates you have so far are pretty far apart in what they were designed to do despite some surface and price similarities.
