Another vote for M390/cpm20cv/cts204p here. Such great steel. Have owned TONS of knives in this (these) steel(s), and it never fails to perform. Close second would be s35vn, followed by 154cm. Love the ease of sharpening in 154cm, and I'll always take s35vn for a good "in between".
M4 and M390/CTS204P/CPM20CV and CPM-154 are my favorites. But I was told I could only buy and use one for ever I would probably go with CPM-154, great overall steel and super easy for me to maintain.
