On the Hubitat side, I'd say that's probably accurate. However, if you have Hue, the bulbs do pair to that network fine (again wouldn't use them directly on Hubitat due to Zigbee bulb routing issues that these may or may not suffer from, but the trend is not on their side). However, even there, I've noticed they're a bit slower to respond to commands than Hue bulbs, so I can't cycle through scenes too fast or they don't seem to catch up. Their color bulbs also report as being color only and not color temperature (shades of white) capable, despite the fact that I think they really are, so they can be a pain to use in "white" scenes (oh, and their actual color temperature bulb had three distinct temperatures, not continuous variation like the Hue Ambiance...I guess their white bulb is fine, but the Hue White isn't that expensive either).
So...yes, mixed bag all around, but not completely unusable. 
And as I've said, if you do have a Hue network, the "steering wheel" can be joined to that via TouchLink and then paired with up to so many bulbs to be used for direct manipulation of them. Again not fantastic if the bulbs are also on Hubitat, but not too different from using a Hue Tap or Hue Dimmer on Hue.
