The 686 is the finest .357 on the market. The GP is a close second. Is the S&W worth the extra money? Yes in my opinion, but you have to see if the slightly better S&W trigger is worth it to you.
Don't mistake a lower price for a better value.
As a prior Taurus owner, those guns aren't even close to the same class as S&W or Ruger.
