Dave, since I have a Road King, I'll share some of the things I tried to consider. How do you plan to use the bike? I looked at a V Rod, and it didn't seem like it would be very good for a passenger. Plan to do any overnight stuff, none of the 3 you mentioned are as good as a Road king ( had to say that), and although you can put bags on them they look added on (IMHO). How important is actual acceleration? Which one looks coolest to you (other than a Road King, of course).
I think part of what some of the others are saying is that if you answer these type of questions, the ultimate answer should become clear. If it doesn't, get a black Road King Classic, I've heard that 93.6 % of all women surveyed prefer men with Kings.
Good Luck, greg
