I've had all of these (in some cases more than one), except the Sauer. Still have the Tikka T3 and Winchester Model 70. The Tikka is a light stainless in .223, which I've probably put more rounds through than even my .22 (I handload, of course) it's pretty cheap to shoot, has hardly any recoil, and is extremely accurate. But if I had to only keep one, I'd keep my Model 70 Supergrade, in .270win. It's absolutely gorgeous, not hard on the shoulder, almost as accurate as my Tikka, and has dropped everything I've ever shot with it, with little or no need for blood trailing.
