I own both ASI and QHY cameras.  

I do know that both ASI and QHY have the same sensors typically.  ASI tends to be more compatible with USB3.0, as with QHY it really needs specific hardware configurations to work properly.  QHY does seem to require a powered USB3.0 Hub as looking at the logs, I can see times where the QHY rejects connection due to power requirements.

I find that QHY offers more modes (typically 4 modes for the high end sensors).  I like that because I may use it on a brighter target, I can use the photographic mode, or sometimes I need high gain with a lower readout noise mode.  I can pick and choose which mode best suits my targets.
I know it is available on the QHY600m/c  QHY 268m/c QHY 367c.  

I also like that most QHY cameras come with dew heaters built into the housing.  I know ASI now typically offers this, but at the time, they did not.  on most cooled cameras QHY has a heater as standard equipment.  Very needed in my deep south Texas environment.

That's my take.

ASI does not offer this.
