Good choices with the CCK and Artifex petty.
The gyuto's you picked are a great sampling.....my thoughts:
TKC - can't go wrong, solid all around performer. "Pick me if you want a great all around, mostly stainless gyuto"
Masamoto KS - a thinner (funayuki style) profile that many like, great steel, wa handle. "Pick me if you want a great introduction to wa handled carbon gyuto's with a funayuki profile".
Moritaka - KU finish, great steel. "Pick me if you want a KU finish wa handle carbon gyuto"
Ultimatum - Going to have a steel like the TKC, mostly stainless...another great all arounder. "Pick me if you want a stainless wa gyuto with a taller profile"
Fujiyama - Choice of steels to try, all of them great....all will have great F&F....all will have great geometry. The Fujiyama series is a great series of knives.... "Pick me if you want a great knife"
It's hard to recommend one from that bunch....it really is.
Gun to my head....TKC with a fancy handle cause I like western's.
Gun to my head, had to pick wa handle.....Fujiyama White #1.
