Should I buy Gen 1 or Gen 2 Nest Hub?

[DigbyTheDog]

In my area, I can buy a Gen 1 Nest Hub for $79.99 or a Gen 2 for $129. 99. Sleep tracking is not important to me as I mostly want it for being able to see who is at the door when the Nest Hello rings. I usually prefer to buy the newest versions of tech, but are there any features besides the sleep tracking that warrant a $50 difference in price?
