Back to the two you mention I would go with the Weatherby. Sakos are nice but I like to minimize the probability of issues encountered in the field. Sakos being clip fed, sooner or later there will be an issue that is not as probable with a box magazine. You can drop, bend, forget or not properly seat a clip very easily. Box mag is pretty fool proof. You may hunt for years and never have these issues but with a clip fed rifle the chance is always there.
The Sakos I have had were not clip fed, but hinged floorplate like in the Mauser 98 or remmy 700 BDL. Think you are refering to Tikka T3s, with the .
Fot the OP, it would depend pn the caliber to me, if going Westherby round then Weatherby MKV others calibers Sako. Both are fine rifles
