I have Racer Ms (post mounted) and absolutely love them. I've never tried the other two. Another option with comparable reach that are reasonably priced are Dia-Compe 610s. The Paul and Dia-Compe require a cable hanger which some find to be a big deal but it isn't one for me; they would be my first and second choices but I also hate dual-pivot brakes.

One point: all of the brakes that you mentioned are mid-reach (47-57mm) rather than long reach (57-67mm). For some reason many companies call mid-reach brakes 'long reach' these days.
