Bugs come with the territory. IIRC Creative Suite had it's fair share of them, too. But I haven't used Creative Suite in a long time and even if I still had CS6 access, it's a no-can-do on Hi-DPI displays.
Since 2014, PS CC hasn't posed any major stability problems for me on Win10. When I install a new version that doesn't suit my workflow, I uninstall it and revert to a previous PS CC version. I keep several versions of each app in case I ever need them.
