Being able to put a good edge on a knife is almost more important than the type of steel.
That being said today's steels SV30, or D2 are awesome.
Putting a great edge on SV30 is harder to do than on D2 however once sharp SV30 is krazy sharp ans stays that way a great while.
The best sharpening rigg out the is the edge pro, couple that with patients and good steel and you be impressed.
