If light effects are important to you, the Gledopto does well when used with a hue bridge and then you will have a choice of many different apps with many different kinds of effects. And that way the gledopto is still available to SmartThings through the Hue integration.
But there’s no easy way to integrate the effects with SmartThings, so it depends on your own personal preferences.
I used Hueoween, A specialty app, for a couple of years to drive our haunted house effects at Halloween and was really happy with it. But it was just a parallel means of control, not fully integrated.
