So "less wear resistance" means VG-10 is better?
Not particularly. If your knife dulls from rolling or chipping, wear resistance doesn't matter too much. If your knife needs a larger angle to hold the wear-resistant carbides in place, wear-resistance is the pointless benefit of a thicker edge. If you're normally cutting abrasive materials, then the wear resistance can be a boon.
And where wear-resistance is
good and observable, it's normally obtained from hardness - either from the martensite or its carbides. A 10 degree edge of YSS White #1A at RC65 is brittle, but it's tougher than VG-10 at the same angle and a lower hardness and VG-1 is as well.
So VG-1 is tougher than VG-10 at most given hardnesses, can take and hold a finer edge, and costs the maker less money (which is never reflected in those Nenox knives or Suisian Inox Honyaki gyutos...), but if you're using a standard 30 degree (15 per side) edge on your knives and aren't slamming your edges into the cutting board with wanton abandon, VG-10 could be better.
