Fibaro or Smartthings?

Has anyone on here come from Fibaro HC2 to Smartthings ?

I have the HC2 with a minimal setup and have just bought the Smartthings starter kit.

The question is - which one to spend the time on? !!

I have a few Lightify RGBW which I like and I will want to use the Fibaro RGBW units to control LED strips.
