I didn't realize it silently ignored Hue lights even if you specifically chose them. I got the impression from a previous conversation that this was not intended behavior. Have you confirmed that it's not a bug with Hubitat?
For the responsiveness, that's a good reason. I don't know what ST did, but it seems to respond to changes in Hue lights much faster than Hubitat, which as far as I can see seems to just check in once a minute. I have some custom lighting apps based on motion that dim when motion stops after saving light states and restores them if motion resumes before the lights turn off (after a timer), and unlike ST I notice that sometimes Hubitat doesn't save the correct light states if I have a relatively short period before dimming. (I can work around this by increasing that timeout, but if you have something on Hubitat that subscribes to a Hue light changing and it needs to be fast, that's obviously even more different.)
