I really like the SSG, especially with the barrel change system & slightly longer action where you can easily run a 6.5X55. The trigger, safety, and action is excellent (trigger is almost as good as the TRG). But with that being said the TRG is a very close second to Accuracy International as far as my all time favorite. For reference I have owned 1 SSG3000, the STR200, a TRG with 3 different barrels, 2 AWs, & now an AT.
TRG is my pick of the 3. Only down side is having to send it off for a new barrel. Where you can order drop in barrels for the SSG from Benchmark.
