PySide2 (Qt for Python) has been in production where I work (and in the visual effects industry) since 2016.
Since then, bugs have been smashed, modules have been added and improvements have been made. I would recommend almost anyone to start developing with this right away and, like always, report bugs [0] and contribute improvements back to the project [1] (not on github).
