I have a Anryu white, Anryu blue hammered, and mizu blue. Anryu also makes Kumo (VG10 damascus), but I don't have one of those - http://www.masakageknives.com/knives_kumo.html
. OOTB, all three were nice and sharp, and F&F was among the best I've seen for all three. Pretty darn thin behind the edge, no complaints about the grinds. What I say below is bit of splitting hairs, trying to differentiate very slight differences.
The mizu has a resin ferrule and it is visually a bit odd, but the cherry wood handle takes on a nice color through use. The KU finish is my favorite out of any I have seen - very well done, blue hue to it. I like the lacquer (others don't). F&F gets a very slight nod above the others (only complaint I had was step down from wood to ferrule on handle, but I don't care so much about handles, so it never really bothered me).
The suminagashi with KU is a beaut of a knife - very appealing aesthetically. F&F is a SMALL step down from the Mizu - eased/round choil and spine isn't quite as even as Mizu, but probably splitting hairs here a bit.
The hammered is truly unique. I whole-heartedly agree with Melampus above and couldn't have said it better myself. If I put all my knives out on the counter, this is the one that people would pick up and inspect first. It is a bit lighter than the mizu and suminagashi comparing gyuto weights. It is my favorite performer of these three.
If you have enough knives in blue, the suminagashi would be a good fit. If there is no steel preference, I'd grab another hammered. Nothing against the Mizu mind you - just that the hammered is a great performer with awesome looks.
