I have both the national match and the SD3G, my feeling is that the triggers should be on the host firearm that they are best intended, so obviously the national match lives in my precision AR lower but the SD3G lives in my dedicated AR45. The flat bow of the super dynamic to me is similar to the feel of a 1911 and the crisp pull & super short reset make the rifle perfect for tight quarters with fast transitions. I love the curved wrap of the national match trigger around my finger as it gives me the feel of a more consistant pull. If I used the dynamic on a presicion rifle , I probably would not like it as much but for the use that I have now, it is perfect. With all that being said, I have plans to purchase a S3G and a SSA for my two other SBR's and haven't considered another flat bow design but you never know, I may end up with the SDE instead of the SSA
