Huh.. You asked a similar question last February... maybe the answer is kind of the same? Some of us have not had those issues at all so kinda hard to answer..
Check out the release notes:
There has been steady improvements to everything including an update to the Z-Wave firmware which replaced the old buggy DB. Are there still issues? No doubt! Are they getting prioritized and fixed? As far as I know - yes.
Also I would agree with @Madcodger - if you are happy with HS and it continues to suit your needs I'm not sure why you'd want to change? I'm sure HS has seen similar improvements over that time as well.
You might also want to check out Home Assistant - some members here run it in conjunction with HE and there are some nice community integrations available.
In my case I use Node-RED for my rules - I prefer the visual flow paradigm, flexibility and resource offloading it provides at the cost of added complexity of course. Even so HE continues to be the device controller/hub to beat imho.
