I've been using SmartThings now for a while. I really starting to believe it's far superior to Wink in most ways. Even when not bringing up functionality that Wink doesn't have, it just works better. I've never had an issue with SmartThings polling of devices. Basically, polling is what happens when you turn a device on or off from the wall and the Hub has to check with the device what the state(usually on or off) of the device is. It seems like my Wink hub is more often than not wrong. But in the few weeks since using SmartThings I have yet to have it show an incorrect state. The number of options and tinkering that SmartThings allows over Wink put's it really in a whole new category really. The fact that SmartThings has a native iPad app really puts it at the next level. Then when you add the web interface, device handlers and all that you can do with things like that, if you like to tinker or even have the option, the SmartThings hub is the way to go. This doesn't mean it's all roses on the other side of the fence. Wink has a better mobile interface, it's cleaner and simpler if it does everything you want it to do. Wink also has light groups, something not easily replicated on SmartThings. This allows you to with one button to turn a group of lights that you select on and off. If you don't want to mess with the roll your own options like OpenHAB or HomeSeer, then SmartThings is definitely the way to go.
