I use now for at least one year. I can control my heatings, my lights. Integrate late product as Ikea Tradfri really quick. The UI could be bad but it is so easy to integrate with Alexa or Homekit (with homebridge) that we can allow this issues.
A lot of integration
Easy to setup (see hass.io)
Some slowness/issue using the front end UI on different OS
Difficulties to have a nice organisation (UI)
