That's directly addressed in the actual post.

#7> The PY32F030 parts advertise a typical low-power stop mode current consumption of 4.5 µA when using a 1.0V setting with the internal regulator, and I was able to get the part to drop down to 5 µA in my testing. Meanwhile, the STM32F030 uses less than half of that in stop mode
I've had the same experience with cheap (Chinese) microcontrollers - power consumption is usually higher across all modes.

#8I'm not sure why people try and go for the cheapest microcontroller. These things all have unit prices in the single digit dollars or less in actual production costs. Finding a cheap microcontroller is entirely about finding a cheap reseller of whatever you're trying to get rather than finding a cheap part specifically. Only when you get to truly large volumes such that you can get volume discounts does unit price really start to matter.
Especially if you're a hobbyist, price should just basically not be a factor in what you're choosing as they're all in the same ballpark from resellers.

I'd guess the main risk is that these are fairly small companies with shaky financials that may go under.

I don't necessarily agree with their take; When your focus is unit cost, tooling is more important.
But it is true that CH32V tooling is, right now, quite sad. Particularly, the only way to flash these devices is to use proprietary tools. That's a major stopper.
