CV seems a bit easier to sharpen to me. Someone once described Case's SS as feeling "gummy" on a whetstone, which makes sense. The CV has a crisper feeling when sharpening and doesn't burr as much. Sometimes you'll get large burrs with the Tru-Sharp that are difficult to remove.
I don't notice much a difference in the overall obtainable sharpness or edge holding. You might spend a little more time with the SS, but it seems to get just as sharp as the CV. I often swap between carrying stainless and carbon steel versions of the same model and I don't see a difference in edge holding, but my slip-joints only get used for pretty light duty stuff, so YMMV.
