Some seem to have issues. I've been through Wink, Iris, Abode... and my Schlage's work better with the Hubitat than any of them. That said, I have a well-built mesh that I've invested time and effort in.
People say they work "perfectly" on other platforms, but it's just not true. Z-Wave is not always plug-n-play due to the disparity of impediments and how the routes shape up. If you're willing to spend some time learning to debug the routing, it's not hard to identify the problem forwarders and get your mesh working well.
If you want "just works" or "never works" as the only two scenarios, go Homekit! ;p
