I have used my Henckels Professional S Series for almost 15 years. I simply liked the feel in my hand better than the Wustofs when DnVsMom and I were registering for our wedding. I added a Santoku and was pretty happy until a year or so ago when I bought a Shun Santoku. It is now my favorite knife.
I am now on the lookout for a paring knife as the other day I noticed that the handle was cracked on mine.
