For the price and beat most rifles for even many hundred dollars more, I'd choose the Tikka. Excellent out of the box accuracy with the stiff, floating barrel as the Sako.
Very strong smooth action.
I get such a kick out those who want to talk about the "plastic trigger guard or magazine". BTW synthetic composites have been around long enough you really need to start calling it by the right name.
There are many very fine quality firearms (e.g. Glock, Springfield Armory, Benelli, Beretta, Sako, Remington, etc.) that have multiple models of handgun, rifles and/or shotguns that have parts and stocks made from these extremely tough wear resistant synethics that'll last a lifetime.
