GE 12722 doesn't fit-too deep

There are people using the RF9501 as a standalone switch, no problem. As I mentioned, there’s a community device type for the RF9500. If you were going to use a three-way configuration, SmartThings has some issues with sync:

So it really comes down to your specific use case. I’m definitely not saying coopers are the best for everybody using SmartThings. Smartthings does not support some of the zwave advanced features that some other controllers do so that it can treat Zwave and Zigbee devices in a similar fashion. A least common denominator kind of thing. That’s good in the sense that it makes it easy to mix zwave and Zigbee devices into the same group commands. But you do give up some features to get there.
