VG-10 is a little tougher than 154CM or ATS-34. By that I mean it can handle slightly more "abuse" - prying etc. I believe 154CM/ATS-34 can be hardened a little more but not much more and usually isn't.
Many of my kitchen knives are VG-10 or shirogami. I have hacked through frozen food with some of my 15 degree beveled VG-10 gyutos with no serious damage to the edge. A harder and more brittle shirogami blade would develop some chips in the edge. I can assure you VG-10 is tough. On the other hand, I have a TOPS fixed blade made from 154CM that has withstood some abuse relatively elegantly. It has 25 degree bevels, however, so the comparison isn't apples to apples. However I would certainly consider it tough enough.
I have 1 kitchen knife and several pocket knives in S30V and I think they are probably closer to VG-10 than the 154CM is. They seem to feel like each other during sharpening and perform closely enough that I wouldn't know one from the other just from using them. All of these steels perform quite well, both in folders and in fixed blades. If I had to pick my very favorite stainless steels, I think I would opt for VG-10 or S30V on the fixed blades and BG42 on the pocket knives.
