WE (and their budget brands), Reate, Kizer, QSP, Tuyaknife, hmmmm that's about it for the list of Chinese companies I would recommend without reservation.
Actually, Tuya did do a copy of the Giant Mouse GM(1?) before they went through a bit of a refocusing and debuted as a legitimate brand. And I have only handled three of their framelocks, but they're well made and as long as they're testing well with the steel nerds I'd say you would be happy with one of their knives.
Rike also has generally excellent build quality, but they irritated some people by releasing a framelock with some design features and proportions that were suspiciously reminiscent of the Spyderco Tropen, without being a copy of it or even outside of Richard Wu's design language. They were obviously not the same knife while presenting a very 'inspired-by' feel. But their ZD-006 and Thor4s are really nice if a bit thick in the grind.
Kizer knives often require a little bit of spa work and a break in period to settle into the action and lockup that the knife actually has, and I find that they have wildly different tolerance for having no thread locker in the pivot. Some don't loosen up all that quickly, others are important to goo up with loctite once you've fiddled with it for a few days. I also have a tendency to buy them on sale or when I think they're a particularly good deal, but that's how I buy almost every knife. I like how they engage with us knife dorks and try to offer interesting exclusives that we'll be into. There's a reason we snap up the sprint runs and I'm thrilled that there is such an embarrassment of riches for knife likers today.
WE and Reate are the most uncomplicated recommendations, they certainly belong on any top ten list of major production knife makers, and for many people they are easily top five. Any manufactured good might have a few lemons, but in general with these two you should expect a perfectly excellent knife with nothing quality wise to complain about.
QSP is new but I've got a few of their knives and I'm very happy with them. If they catch on and see commercial success I think they'll gain a great reputation. The Pelican and Puffin are my two favorite from them.
Oh Bestech is pretty good too, they're just always missing my short list because I like WE and Kizer better. I do have an MBK Mini Old Guard that they manufactured, it's really good, not my favorite but I like it a lot and will probably keep it even though I rarely carry it. They are very busy with OEM work these days.
Artisan Cutlery and CJRB are another one you don't have to question the materials on. I've had a little vertical wiggle in a couple of their budget knives and I hate wiggle, especially vertical, but it wasn't alarming and didn't seem to cause lock slips. So they're not on my radar because I only have so much money, but the Maileah at $36 for micarta and their powdered steel is a must buy in my eyes. Mine has no issues either.
Oh and Real Steel and Ruike are both good, I like their actions and fit and finish. Real Steel is not messing around with their grinds and action in particular, I bought a G-Frame last week and it's super. Way above it's pay grade.
I would stick to any of the manufacturers that are doing legitimately good work and be willing to spend more than thirty bucks, personally. Finding a discontinued Kizer or WE that's seventy dollars off and appeals to you is my suggestion. Sometimes you can find titanium framelock Kizers for a hundred, and designs that people like too, not just their dogs.
