S30V has had its problems in the last few years, leading to the introduction of S35V....I prefer CPM154 stainless over either of those. Sharpens well and holds an edge forever.
What would you say is problems with S30V? S35VN pretty much mirrors it. Yes it has a few very very small advantages to a degree.
I like CPM154, not to be confused with it's mirror 154CM, they are all for the most part the same as VG-10 and ATS-34. Yes the process is different and it does yield a few benefits.
Bottom line is Proper Heat Treat and Edge Geometry will trump all others not so properly done. I wouldn't say no to a finely made knife in any of the materials you listed including carbon.
