16 Zone Iro or Smart Controller Gen 2?

I am looking to purchase an Rachio device, but am having trouble determine the feature differences between the 16 Zone Iro or Smart Controller Gen 2. Can someone tell me what the differences are, especially considering the price difference?

@ahowse

This post has a decent breakdown of the new gen 2 features.

Please let us know if you have any other questions or feedback!
