Thank you mame1616! I really appreciate your feedback. I am new to looking at chickens for qualities other than "cute". These are my first non-hatchery chickens. I am going to a show in May (not taking chickens) to see what is there, who is there and if I can get a feel for shows to see if it is something I would like to do. Even if I don't end up showing I would like to breed some good quality individuals.I like all three! How are the toes? If I had to pick, I would go with the ones with the best type first - see that nice upside-down trapezoid shape in #3? - then with color - the white in the beard of #2 is less desirable, although it can be used for producing better females.
That being said, males are hard. They're not really set in their adult plumage until they are a year. That's why you go with type first - the stuff that you look at if they were a solid color. Toes, skin color, comb, eye color, the trapezoid shape, width in chest, weight, etc.
I do see the trapezoidal shape in #3. Especially after you pointed it out

I might post my girls too. I think they are nice looking as well, though two of the females had curled toes at hatch and even though I taped them they are still obvious now. This could be an incubation/humidity issue but I am not sure. I have noticed that three of the girls have some dark/black flecking in their hackle feathers (not their beards) even though over all they are quite light in color. The two that don't have the flecking are smaller in size and have a darker overall coloring. Body shape isn't as obvious to me right now.
I know with time I will be able to see what a good bird looks like. Right now it is difficult and I have a hard time weighing faults vs strengths. What aspects are more important, etc.
