Both of the brands you've mentioned have quality and durability as features. They'll both cut, and likely continue doing so for a long time - as evidenced by the number of folks telling you to pick up a used example and they aren't wrong either.
However, developing an eye for used knives is an art and a science that isn't picked up overnight. I've been looking at them for about 4 years now and still feel like I have no idea what I'm looking at half (or more, probably more) of the time.
So, I'll focus on the two you mentioned. Rosecraft knives are designed by a well-known American knifemaker, Andy Armstrong (he is most known for designing Rough Ryder, another affordable option, knives) and made in China to his, so far, very exacting standards. If his unique design sensibilities don't turn you off, and neither does the country of origin - they are a very solid choice. Sharp - I'll say that again, SHARP out of the box, excellent fit and finish, and, in my opinion, a great value. I have a variety of Rosecraft knives, many of them seconds, and they are all infinitely functional and nice looking to boot. I'll note that Andy has claimed to have aspirations to open an American cutlery factory at some point in the future, if that changes things for you (I have no idea why it would, but there you go).
A bizarre picture of an excellent Rosecraft Barlow knife. All fault lies with the photographer, the knife is perfectly splendid!
Bear & Son knives are made in the USA (Alabama?) and offer what is most likely the most affordable line of American-made traditional knives out there - but that's not to say there isn't a cost. I've found fit and finish to be on par with, sometimes below, Case. I've yet to find any flaw that would impact a knife's usability, but niggles like unintended recurves or bellies on blades that should be straight, gaps between the spring and liners, slight blade wobble, etc, are common and should be anticipated. At the end of the day, and if that matters to you - you're getting an American-made knife at a great value. How happy you'll be with one depends almost entirely on how nitpicky you have a tendency to be about such things.
A Bear & Son-made, Remington-branded Barlow knife. Look closely and you'll see some issues. Issues that have never prevented it from doing its job, but issues nonetheless.
I can't help myself. Apologies in advance. At four times your budget, I would not recommend picking up the GEC-made, Remington-branded Granddaddy "Silver Bullet" Barlow produced in 2022 - though it's easily my favorite Barlow, and most carried knife overall. Like I said, I do not advise going down that particular rabbit hole... yet - but jeez Louise - what a knife!!
The author/photographer acknowledges that he is completely in the tank for this knife and doesn't feel the least bit bad about it. Hooo-eee... just look at her... wow.
