I own both. The Sako has no plastic components. Rather, it is all stainless steel. The Sako action is also stronger, although, believe it or not, I find the Tikka action to be smoother. Both guns have essentially the same barrels, but stock designs are definately different. As to whether a particular stock may provide less perceived recoil is really dependent on the particular fit to a particular shooter.
Are Sakos really twice the gun? Or are Tikkas really double the value? Only you and your wallet can answer that question, although I believe the answer to both questions is yes. :wink:
