All wifi implementations are proprietary, and most are cloud dependent at some level. If you go wifi you need to be OK with cloud control, or maybe/maybe not being able to control the wifi device locally long term.
For what my two cents are worth... I agree with the above information. One major consideration or selling point to me, switching to Hubitat was local control. With my novice perspective, I wanted to retain as much localized control and avoid internet dependance as possible. If your home or facility has power to operate the lights etc, it has power to operate Hubitat. Recent power outages in our area helped solidify my position with the reliability and strength of Hubitat's local abilities. For those reasons, I have a combination of Zigbee and Z-wave devices . (Full disclosure, I do have a very few wifi devices as well which are integrated via Alexa)
With that said, this is very much a personal decision as you will find pros and cons for all platforms.
