I first had my trigger done by Springfield, and then recently installed the new RA trigger. I have only dry-fired the RA trigger; haven't hit the range with it yet as there are currently no sights on the gun. :-\
Anyhow, they break at about the same weight; RA trigger might be ever so slightly lighter. The biggest differences I can see so far are whether you want a 1 stage (BS) or 2 stage (RA), and of course the cost, with the RA trigger being over twice as much money.
