As others have mentioned, the Lutron Clear Connect RF protocol is fast and incredibly reliable. Having a SmartBridge Pro to manage all of the switches, also means you have another very well supported means of integrating these devices with other systems than just Hubitat, if desired. Lutron integrates with Amazon Alexa, Goole Assistant, Logitech Harmony, SmartThings, Nest (for the time being), and many others.
So, having a standalone lighting system, that integrates locally with Hubitat with amazing performance, is a huge Win-Win for me.
Oh, and Pico remotes are absolutely amazing. I bought my SmartBridge Pro2 just use Pico remotes... then I replaced all of my flakey old GE Z-Wave switches/dimmers with Caseta switches/dimmers and have never been happier. I only have two active Z-Wave devices left in the house, and those will be replaced soon as well with Zigbee counterparts.
