I view the T3 action more for bench work given you can't get your fingers in it as easy. The tighter ejection port makes it more accurate - which I think the T3 wins.
The Sako 85 is 1300+ and is built tough, so is the 75 - metal magazines, and all metal. I see if more of a well built big game rifle.
The A7 is the in the middle compromise. without the dumb sako ring mounts but the big game action, and a good amount of the T3 recoil lug features. So if you want a cost effective production rifle the A7 is a good one.
NOW the accuracy thing - Sako's are throated differently than any other rifle I've had. And they definitely like a specific bullet weight. Try to make them shoot something they don't like and you'll have the VaHillbilly experience mentions above. And in fact that's the first thing the Sako Rep will tell you if you ask him what weights your rifle might like.
