K - has nice even patterns
A, B, and I - have great face markings and decent body patterns
the black scales will darken in time so maybe its better to pick one with a lighter black scale such as I
I believe "I" has the best face markings and would go with that one
This video might help you

Kujaku seem to grow into the body shape so i'm not worried about that at the moment, Beni and Pattern is what i'm looking at and from what i see, L F K and M carry what iI look for in a kujaku.
I like M the best.
Thanks for all the advice, what am I looking for when judging the sheen? The glow/brightness on the skin?
I think my favourite on balance is I, I really like the markings on the face but maybe lacking a little in the back of the fish? I also think it has one of best body proportions although not the biggest of the group.
I also like F as it has a sort of reverse tancho thing going on. Not sure if I've been looking at the video/picture too much and I'm seeing things but it looks like it has an "M" on its head? I also really like the body pattern, probably not traditional but well balanced. My only concern is whether the body shape and head is a little narrow?
I like A. big head, clean, best sheen as far as i can see
In my opinion go for the one that is metallic. They all look beautiful. Each koi fish have their own beauty. Good luck
Well in my opinion i pick C. I’m not a pick fan of too much orange patterns. But use your heart and go with it. Each fish has their own beauty .
I say K all the way. 4 step pattern (orange just above the tail). Step patterns are the most desirable.
I agree with Rich, and it has excellent symmetry on the markings port and starboard. I also really like the facial pattern on A. Which one did you like? Ultimately that's what matter most.
