I've gotten some Blue Pills with (properly labeled) CKS32s on them, which might be of lesser quality, but I've also seen people reporting getting Blue Pills with (properly labeled) GD32s, which are higher quality than the ST part, at least in the sense that they run successfully at higher clock speeds. (I couldn't tell you if they have more problems turning on many peripherals at close-together times, or if they have more noise on their ADCs, or something.)
