If you're purely looking for performance, premium brands just aren't the way to go, or at least their high end offerings aren't. Don't get me wrong, there are touches that many premium knives offer that, as an enthusiast and collector, I absolutely love (Viper melts, rounds and crowns every edge except the cutting edge and I love the aesthetic and in-hand feel that gives, just as an example), but if you're looking for a simple cutting tool, even if you want a premium super steel to go with it, you don't have to spend a ton of dosh to get it these days. My Spyderco Urban sprint in K390 cost right around $70 and that steel just cuts and cuts and cuts.
