A little late to the party, but for what its worth:
(I didn't read all 9 pages so sorry if some of this is redundant)
I've got a Tikka T3 superlite in 270 and Savage 16 LWH in 308. I love both of these guns and both are great shooters.
The savage shoots lights out with 150gr Honardy SST. It pretty easily shoots 1/2" with a good rest...which is kind of mind blowing to me for factory ammo and the price point the guns at. I really like the 20" barrel on the Savage as well. The fit and finish however are little lacking on the savage. The bolt can be pretty tight and sometimes it feels like its binding against the top of the magazine. It can be a little finicky when trying to feed a new round out of the magazine as well. The fit of the magazine and stock also leaves a little to be desired.
I've got way more money tied up in the Tikka. It shoots 1" pretty easily with 130gr silvertips and the bolt is ridiculously smooth. Factory fit and finish are nicer than the Savage, plus I've changed out a decent bit of stuff on mine so overall it feels like a much more solid gun.
If I had to pick just one it would be a hard choice, but I think I would end up going with the Tikka for how smooth the action is if nothing else.
On a side note, I've never owned a Montana but a couple buddies have them in 308 and they love them. I've shot them before and they seem like well built guns.
For reference:
Savage is stock with Talley Lightweights and VX-1 4-12x40 LR and tips the scales at 6lb 11oz with a full magazine
Tikka I slimmed the stock, bolt fluted, bolt handle skeletonized, Mountain Tactical bottom metal & bolt shroud, limbsaver, 16 Bore Talley Lightweights, Swarovski Z3 3-10x42 and weighs in at 7lbs even with a full magazine
