I guess the fact that some manufacturer integrations are flaky is hard to reconcile for me as far as the promise of "having multiple kinds of smart devices isn't really a problem". Regardless of whose fault it is, those flaky devices contribute to a less stable system.
It's been a bit since I was operating it, but I did at times certainly have issues with updates—perhaps just individual plugins or system updates that created an issue, either way, still a situation where I had to sit at a terminal and debug. I only ever ran the Docker version, not the OS, so perhaps this is less problematic in a more completely controlled stack.
I have been using Home Assistant for more than 5 years. The stability of the system has improved a lot in the last year. I don't recall the last time I had to reinstall or restore a backup.
At the beginning (0.7 or maybe even earlier) I remember to have to reconfigure or reset my instance a few times a year. Those times are long gone.
For my flaky devices, it it not a manufacturer integration, but over Zigbee. It's definitely the device as my other Zigbee devices are solid. Others have reported issues with the device in question (Aqara Temperature and Humidity Sensor)
I ran the docker version on a QNAP for a long time, now on a Home Assistant Green.

I don't think I'm alone in this view, broadly speaking: https://www.reddit.com/r/homeautomation/comments/18hvl3b/i_g...
