as far as the "all-weather" rifles go, do you plan to hunt in the rain in an open stand? if you do, they're not a bad idea. If you are more likely to stay inside when you wake up and its pouring rain, they don't offer much benefit. I usually take one just because I don't mind 'em getting wet as much as I do a blue/wood gun.
Have you handled these guns that you are considering? that might make your mind up real quick. If I was going to drop $1500, I'd take the Sako out of the choices you listed. You can pay a lot less and get a very serviceable gun, but you do PFWYG.
In reality, I've been hunting with a couple of savages over the past few years, a .250 and a .308. they are dialed in, and I don't mind getting them dirty and scuffed up. The .308 is a better all-around gun, but I usually end up taking the little .250 pop gun just because it's such a nice gun to shoot.
