I'll comment only on rifles I have personally shot.
Good: Used a Ruger 77 270 Winchester one season. Consistent shooter, easy handling and killed a couple of 8 Points with it.
My Winchester Featherweight 270 WSM has been shooting 1/3 MOA almost 2 decades now, but only after my gunsmith added a target crown, new trigger and Acraglass bedding. So customized a bit.
Wanting to improve on that, after much research I narrowed it down to Browning X-Bolt, Sako 85 and weatherby. My dad and I both had hunted with Brownings so I was leaning toward the Sako 85. High dollar guns were above my pay grade. I was about to buy the Sako when Sauer und Sohn came out wit the 100. First time in my life I had ever seen a Sauer I could afford! They described it as "an entry level rifle into the world of Sauer"; that claim turned out to be classic understatement. So I got curious and found this newly designed rifle had a bunch of unique engineering features. A sleeve between the barrel and reciever I had never seen before. Everest Bedding I have to this day never seen anything like it. Noticed the barrel was same as used on their $4,000 rifles and was perplexed as to why Sauer would even be interested in going into the lower priced rifle market. Seemed too good to be true. So read some reviews, all of which sounded like love letters. Then found some new owners who were posting targets which again appeared too good to be true. Then a guy from Australia posted targets from the cartridge I was considering. Couldn't stand it, so rather than getting a Browning, Weatherby or Sako, I ordered one. Best shooting rifle I have ever had. Seems "Entry into the world of Sauer" is the German way of saying "gateway drug". I now have 3 of the things. Groups under a dime at 200 yards on all of them.
The bad: Thankfully I have avoided wasting money on rifles that won't shoot or have quality control issues like Christensen. You either get a good one or as you have all seen by now you get a nightmare that may or may not be fixed before you demand your money back or have to sell at a tremendous loss.
But a few other factory rifles are problem prone as well. Some just are not designed or produced to shoot any better than 3/4 MOA but Joe Deer Hunter seems to be satisfied with that. So they sell a lot of them.
The ugly: Can't say ugly without thinking of Savage. Some shoot great but they are ugly. Life is too short to hunt with an ugly rifle.
I think today I would add Bergara to the good list. But my safe is full.
