I honestly think the best option is to go with a mainstream second hand frameset and then build it up with your own "chinese" components.
Anyone that is going for whole bike builds is a super fred at this point since I would have to immediately replace the bars/stems (44cm lmao) and cranks (175mm lmao).
I also have a lot of wheels already so the wheels/tyres that come with it would go sitting in the corner.
If it comes with a powermeter i'd have to sell it since i already have powermeter.
The saddle is also useless since it won't be my preferred saddle.
At that point i bought a whole bike and only using the frame and the groupset.
This post illustrates an interesting point in that what is 'good value' changes with local market conditions.
Whether an open mould bike can be good value depends on what you're looking to get from it, and how that compares to local alternatives, particularly second-hand.
Here in Australia, ever since Shimano and SRAM prevented international retailers from selling their products into Australia, it's been much harder to get cheap groupsets. I first built a Chinese bike in 2014 and was able to get a great deal on the new (at the time) Shimano 105 5800 which I was able to import from the UK. There's been many reports of cheap closeout SRAM Force eTAP AXS D1 groupsets going cheaply in the EU and USA, but no such deals in Australia. Being unable to take advantage of this makes buying a Chinese frame relatively less appealing, since by the time I buy a groupset and wheels, I'm not so far off the price of a big-brand bike.
Rim brake bikes have also plummeted in price second-hand here - there'd be no point getting one from China any more. Late-model high end rim brake frames, particularly if they're not at the top level of desirability (for example, a Giant TCR, Focus Izalco Max or Merida Scultura) cost less than a new Chinese frame.
If L-Twoo and Sensah make some good groupsets then it could swing the balance in favour of Chinese parts again. I'd be interested in doing a Hygge/L-Twoo/Elite Wheels/Magene PES build to sneak in a carbon disc integrated bar frame, electronic groupset, power meter and high-end wheels for ~$2300 USD, but it feels like a pretty big risk to take.
There's still plenty of good use for me for Chinese products - particularly getting kit for fairly standard rim-brake bikes. Being able to get a good quality carbon seatpost, saddle and bars costs a ton with western brands, AliExpress is now full of great products on that front.
