CRKT use a lot of AUS6 and AUS8, both are Japanese made steels. The difference between makers who use the same steel is how they heat treat it and if they get the most out of the steels potential ( ie edge retention, hardness, wear resistence etc.). The makers edge profiles and blade grinds will also have a dramatic result in the knifes performance. CRKT often chisel grind their blades, which is not suitable for most of my requirements, thus I don't purchase them. Personaly, Im not a fan of AUS6, it is easy to sharpen to a reasonable sharpness, but doesn't hold its edge very long. AUS8 performs a lot better, more like 440C.
Expensive ( huge middleman margin ) sounds like Wellington surplus, I always look at the US online shops like New Graham, who give great service and prices.
