You should read more posts before posting such a poll. Here on THR, I think more prefer 3" than anything else, overall, and there is also a small but loyal following for the single actions, which typically are made in 3", 4-5/8", 5.5", and 7.5". A few like 5" in DA sixguns, usually customs, but both S&W and Ruger have made a few 5" sixguns, and S&W lists one now. I bought a 6" Security Six with the intent to have it bobbed to 5" someday, and a 4" Security Six and a take-off 6" barrel, too, so it can perhaps someday be a pair of 5" Security Sixes. Perfect!
