I have owned 4 Sako rifles, the first one bought around 1980, & have handled & shot Tikka rifles(which are owned by Sako). I can highly recommend Sako & Tikka rifles, although I prefer the look of Sakos.
Blaser rifles I have no experience with, although I know they are well finished & accurate. 2 years ago I was looking for a new centerfire .30 caliber rifle & went with the Sako Bavarian in .308. I ruled out the Blaser because of the weird straight pull bolt action & the price, which was nearly double the Sako.
I have been more than impressed with the Sako Bavarian in .308.
