I think one of the problems lately is that the information is a lot easier to come by. Back in the day you used to hang out at the gun counter and there were no "bad" guns, but nowadays it seems as though everyone knows "a guy" who has had a bad experience with brand X.
My experience has been different for the most part. Remington gets a bad reputation due to a few product recalls and some mostly unsubstantiated videos and biased reporting. The SPS line of rifles and Express shotguns get crapped on for poor finish, when they're clearly intended to be "entry-level" options and the functionality is unaffected. Yes, they're a step back in overall feel, but they're SUPPOSED to be a step back. The CDL and Wingmaster lines are still nicely finished and well-built as previous, and the safety of the design has never really been in doubt. Want tight groups of of the box? No problem.
Ruger IMO has only gone uphill since the original M77. I owned one, not bad. I owned two Mk II's, wasn't a huge fan of them are they weren't the most accurate or prettiest gun out there but they were solid and the scope mounting was excellent. The newer Hawkeyes have a better trigger out of the box and just handle a bit nicer. Continual improvement. The No. 1's are sweet pieces.
Savage as well has elevated itself from mere entry-level player. You used to buy a Savage because it was cheap, but the entry models have gotten better. The accu-trigger and accu-stock have made huge improvements in performance in their price range and they've started slapping some decent furniture on some of their models. Yeah, the bolt is still ugly but it works, it works well, the price is right, and the trigger and stock innovation is making regular shooters more consistent and more confident.
Winchester gets a bit of flak for not being identical to the original pre-'64, but speaking as someone who has used both old and new, I preferred the handling of the new. I preferred the wood on the new as well, yes, it is nicer, at least on my sporter compared to my Dad's. The metalwork shows less tooling marks, and the bluing is just as nice. Recoil pad is light-years ahead. It's more accurate. My trigger is nicer as well, albeit more complicated. Based on the overall quality of the gun, I have every confidence in the triggers ability not to explode into a thousand pieces should I require a backup shot on an angry bear, should I be so lucky.
Weatherby is an interesting one, since the Vanguard used to be the poor-man's option. The performance of the Vanguard however, is good enough that they cover it under their accuracy guarantee. My Vanguard trigger is probably one of the best out-of-the-box on any of my hunting rifles. Breaks like glass, super crisp. Mine shot just over MOA with factory 115gr. and 100gr. bullets. The range has expanded and shrunk depending on the market conditions and what's popular at the moment, but they seem to be great shooters and appear to be breaking out of the "poor man's Weatherby" stigma. If the stock fits (and you can deal with the weight of the thick barrel), wear it.
Marlin, not much experience but people are singing the praises of the XL7 and XS7 models as entry-level rifles, on par with Savages, which IMO is not bad company to keep in that price range. The people who've showed up at the range with them have been very happy with the performance per dollar, that's for damn sure.
