Without trying to get in to too much of an argument, I don't think a knife can be considered a "user" unless it can be used and neglected without worry for maintaining it, which in turn means I think no "user" should be anything other than stainless steel. Now, don't bother telling me I'm ignorant or that carbon steel takes little, if any, care, I'm fully aware.
Even with the "wonder" stainless steels, the best carbon steels always seem to be better than the best stainless steels. Just go look at the toughness differences between the Crucible carbon and stainless steels. That said, most of the popular stainless steels these days have a good balance between toughness, edge retention, ease of sharpening, and corrosion resistance, and are well suited to just about anything we will ever put them up to. Except for steels like S90V, which are about as hard to get dull as they are to re-sharpen, not a good, balanced steel, IMO.
