"Real" Japanese Santoku knives don't have that Granton edge, and I'm not sure it's absolutely guaranteed that things won't stick if you're using it. Some things may, some things may not. But stuck things are probably easier to get off, with those air pockets.
A santoku and a chef's knife are used for much the same things, but a chef's knife, being heavier, is better for more resistant objects. And you need a longer bladed chef's knife when a shorter blade won't make it through what you're cutting.
I usually use a 6" chef's knife in my kitchen, but I'm cooking for only two and I have small hands. If I had larger quantities to prepare, and a bigger prep. area, I'd use a larger knife. (I do, sometimes.)
My husband likes his santoku (smooth blade) best because it happens to have a bigger handle than most of our knives, and it fits him--it is "his" knife. (He also uses the 8 inch chef's knife more than I do.)
I don't use a butcher's knife--I buy precut meats. (And I do go to a store that has a real, live guy behind the meat counter.)
Main thing is, use what works best for you, and keep your knives sharp and clean them immediately after use.
And be prepared to replace paring knives, if you use them. They are escape artists!
