From a design aspect all three are very similar. Not a huge difference, not enough IMO to sway one over another regarding performance.
All are reputable enough companies in their own rights regarding overall build quality and heat treatments.
From a steel aspect; all 3 will take a razor sharp edge; cold steel uses 4116, which will give you a stainless steel, so less maintenance needed in that regard, and the much higher chromium and moly levels with a small bit of vanadium added will help to keep a dulling edge toothy enough to still cut, plus it's tough, but with the much lower carbon levels (half that of cro-van), expect any time saved due to rust resistance to be made up for with a more frequent need for resharpening...
1095 cro-van then is a juiced up 1095, exactly what the makers intended when they designed it, and a large part to the kabar reputation; small amounts of chromium, moly, vanadium, and nickel added make an even better edge holding, toothier, better working edge when dulling, slightly stronger and tougher version of the original, that is also ever so slightly more resistant to rust, (though hardly stainless, just wont rust quite as quick)...
4116 might be less prone to chip with it's lower carbon as it's been used as a decent steel for stainless axe heads, but 1095 (let alone cro-van) is hardly a steel known for chipping much...
