Having had Case peanuts in both the CV and True Sharp, I found a bit of a difference in edge holding if I put them to the test side by side. This involved sitting at the kitchen table with a supply of hemp rope, newspaper, and a magnifying glass. The CV will hold an edge better, but you have to push it.
In edc use, I don't think the regular knife user will be able to tell the difference, unless he works in a warehouse and cuts alot of cardboard or simething. I couldn't. And that was using a true sharp as well as my CV, gutting pan fish, cutting twine while tending the tomato plants, and sharpening the end of stakes for same, opening the UPS boxes and mail. The true sharp preformed as well as my old sak, and thats a pretty reliable tool in itself.
I think you should get the knife that appeals to you, and don't worry about the steel so much. If you can, go shop where you can pick among a couple of the same knives. Case is made by human beings, and sometimes one will be a little better that another in fit and finish. Being in South Carolina you may have some some humid hot summers. The stainless will be easier to maintain, especially if you spend much time out on Lake Wylie.
