AEB-L is a great, great choice. If you can't find it, 13c26 is pretty darn close. While I have zero experience with the S35VN, the reports are awesome. You couldn't go wrong with either, and I would add Elmax as well. If I was making a stainless chef's knife for myself, I would probably go with AEB-L/13C26 or Elmax. I am simply amazed at how well AEB-L takes a super fine edge, and keeps it very well. The corrosion resistance is superb. I think that many knifemakers would probably go with S35VN over the others mentioned, it is very popular now. You can't go wrong with any quality stainless out there. I'm just not a fan of 440 and 420 series stainless.
