Personally, I think 3 is my favorite as far as form goes, with 1 a near second, except for that comb. In my own birds, early maturity is something I heavily pick for, and I've often seen my cockerels "grow into" their combs, so I'm not bothered much by it, even though I prefer a smaller comb (it will be smaller after their first winter

) but this could very well just be me.
I like the saturation of color on 4, but to me he just doesn't have the body to back it up.
To me, 2, while he has some very good traits, he does also have the noticeable flaws you mentioned, and I would hold his flighter-than-the-others temperament against him.
1 I still like very much for his size, good type and very good color. looking back, he might have the best color of the bunch.
So, to me, it would be 3, 1, 4, 2
And if I lived close enough, I'd kidnap 1 for my own flock
