To get a "better steel", determine what uses your knife is most likely to see and match your steel choice to the probable uses. Steels used by companies like Benchmade, Kershaw, Spyderco, CRK, Strider and other top end production brands are quality steels that often have specific characteristics that make them very suitable for a certain range of uses and less suitable for other uses.
Spyderco's H1 and BM's X15 are intended to provide corrosion proof blade steels for use in corrosive environments. ZDP189 is extremely wear resistant and has outstanding edge holding properties. That makes it particularly good for pocket (or larger) slicers but maybe less good in corrosive environments or for rough outdoor use in larger knives. 154CM, VG10, S30V, and CPM D2 are all good combinations of edge holding and toughness that make them suitable for most people's EDC cutting needs and they're still pretty easy to maintain. Some of the newer steels like S90V and CPM M4 are reported to be tough enough for heavy use and still have the edge holding of something like ZDP189.
