big fan of shun
among the "middle priced knives" i would rate the shuns "the best" of the bunch. this is based on the fact that i have A LOT of knives (over 150!)
and have used them all and lived with them (as opposed to someone who has "used" one at a friend's house or something), often using three or more
in one cutting session to compare side by side the different brands of knives
under the same conditions. for example, i will hand slice potatoes for chips. (yeah, i could use a mandoline, but where's the challenge??)
the shuns and the globals do a great job, the wusthof and the henckels did not ... too thick of the blades and too abrupt an edge. the beautiful polished sides of the german knives make wet veggies (like potatoes and cucumbers) stick to the blades, slowing down the slicing. try slicing ten pounds of potatoes for handmade chips with german steel and you will soon reach for the mandoline. not so with the japanese steel (well ... mebbe ... mandolines are still easier))
the japanese blades stayed sharper longer and sharpened easier with just a few strokes on a ceramic stick. of the four, the wusthof was the hardest to get up to sharp (i can't believe people think the wusthof is wickedly sharp compared to something like a shun!)
the handles of the wusthof classic and henckels pro-s were comfortable to me, but the culinar and 5 star feel weird. the globals drove me nuts by being too thin (except for the forged models which feel more "normal") but the shuns, with their fairly straight handles, offered the most varieties of grips.
so .... with their thinner blades, extra sharp edges, non-sticking sides, and comfortable versatile handles, i would rate the shuns higher than the brands you mentioned. (not to mention that alton brown liked them before they sponsored him!) don't overlook the MAC line of knives as i rate them over the ones you mentioned as well, and if you HAD to buy german, the messermeister brand does everything better than the wusthof or henckels.
just my two cents.
