LBoth are excellent steels... For what it is worth Mike Stewart (owner of Bark River) himself has stated that 3V is the all around best knife steel there is. I read it in his subforum of KF. That was maybe two years ago. His feelings may have changed since but I havent seen much to say otherwise. He is very active there and I am sure if you asked, he would guide you to the correct choice.
Also I have tried my hardest to force a patina on 3V and exposure to every friggen food item, raw meat, condiments and vinegar didnt leave a single spot on it. Guy from Survive Knives left a 3V blade on the exterior window sill of his shop for a month or so, exposed to the elements. It corroded, but cleaned up bretty damned well considering its a carbon steel. With 7.5% chromium and 2.75% vanadium 3V is alloyed enough to probably be considered a semi-stainless. Its vanadium will form carbides and leave some free chromium to increase corrosion resistance. The CPM manufacturing process yeilds very fine grain structure and nearly homogenous distribution of each element in the steel, which increases corrosion resistance too.
3V is my favorite steel for fixed blades and I would love to see some folders made of it.
