I own all three and like them all!
With that said, i have had a few problems with each.
I have had a remington with a chamber that had a very badly shattered finish!
A fired/ejected case could not be rechambered. Only after full length sizing could they be chambered again. A pain! But the rifle (35Whelan), was one of the most accurate rifles I ever owned! This rifle would shoot honest to goodness 1/2" or "better"!!! At 100 yards. Group after group! It was stunning!
I bought a Ruger M77 in .338 Mag that was so poorly finished, that every time I sycled the action, the bottom of the bolt face would machine/scrape a significant amount of metal off the magazine follower.
So much so, that it caused a couple jams between the case and chamber when I closed the bolt! That was ridiculous!
I polished that action for hours to get a decent function of the bolt. That rifle never shot all that well.
I have two M77,Mark 1's (tang saftey)and love them! Sssssuper smooth Mauser style actions! Great shooters as well.
I have had a few real cheap looking Savages, but they all shot well.
Two years ago I bought a 110BA in 300Win Mag. That rifle shoots super good! I have taken it to 2000 yards, and shoot regularily at 1760yards when weather conditions permit. I never thought I would be shooting at distances like that, but this rifle makes it way easier! The recoil is no more violent than a light loaded 7mm-08!
All in all, I believe that manufacturing mistakes happen. Reguardless of manufacturer name. Just put it into perspective.
The biggest problem I have seen is companies no taking responsibilty for thier lack of QC. They try to speed up production, reduce manufacturing costs, and charge us like they hand lapped every part of the rifle!
All they need to do is give the consumer "value" for thier dollar.
