I'm partial to H1...it is reasonably priced (to people like us at least), sharpens pretty easily and is basically impervious to rusting. The only real downside that I can see is that it does seem prone to scratching. VG10 is probably my #2 choice (Spyderco VG10 that is), easy to maintain, gets nice and sharp and doesn't cost so much that the knives become overly expensive. I'll go ahead and put S30V in a #3, I don't own any Spyderco S30V, but my experience with KAI S30V has been excellent, the rumors about it being so hard ot sharpen I really don't think are accurate at all.
