AmsOil is probably hands-down the best, but there are so many great synthetics out there. Royal Purple, Mobil 1 (which I use), RedLine, and the list could go on. I don't know much about the quality of the H-D synthetic. AmsOil can just be a pain to get your hands on, so that is why a lot of people use Mobil 1. I buy mine, believe it or not, at WalMart. I, and many other, use it in the crankcase and in the primary.
Best oil I've every used or had analyzed was made by a company called Specialty Formulations. For my bikes, I use Mobil 1 Vtwin because I can buy it from the local Autozone.
