Google Home is going towards a cloud to cloud solution which means that local controls will be tedious. For the Vera to work, it needs to go through the Vera server which is the concierge. Amazon Alexa has not done this and a Hue emulator still works as a bridge. The Smartthing is an almost all cloud device so it will work though I encourage you to read up about it. I am fundamentally biased towards going away from anything cloud based for reasons of speed, security, reliability, privacy, etc...
