S&S have smaller primaries and a 2.5" downpipe instead of a 3" like the rest, but i have not seen any examples of that being a factor in holding the car back as far as power goes. i run S&S and love them. they are definitely one of the best sets you can get. ZZP are going to be the most expensive of the group, but they supposedly got rid of all the problems of the other headers have (which i dont believe for one second).
you also forgot SLP, which are better quality pacesetters.
its really down to what you want to pay for how easy of an install you want.
