We monitor all channels and answer them with equal diligence. Around UC / DevSummit or major releases our responses might be delayed, and if a user wants immediate help, they must call the tech support.
That said, you can feel free to post questions or comments at either locations. I would prefer GeoNet as most users frequent here, and when your workflow and question involves multiple ArcGIS technologies, you can appropriately tag those teams in the same question instead of repeating them everywhere. Further, you can write blogs, submit ideas, conduct polls and involve the community in a richer manner through GeoNet.
