Global are decent but they're far from the best. Even that Hattori forum knife (which is a significantly nicer knife than any Global) is probably not the "best," in that there are higher-end alloys and fancier handles out there. Calling Global the "best" is like saying a 370z is the "best" sports car. It's a perfectly fine mass-produced product, but there is a world of products which perform better and are better-finished, albeit at higher price points. (I'd argue, for that matter, that Global is not even the best knife in its category, since Shuns are made of superior steel and are much nicer looking IMO, plus have excellent customer support through Kershaw.)
What's funny to me about your post is that you inaccurately complain that the Hattori knives do not identify the material they are made from (in fact that page clearly states they are made from VG-10, a well-established Japanese stainless steel that gets very sharp, holds an edge well, and is highly corrosion-resistant), when in fact Global are the ones being mysterious ("Cromova 18" is a proprietary alloy and thus its precise ingredient makeup is unknown - overall it seems to suffer from poorer edge retention than VG-10, in any case).
