Dear Meh, sell me on which Google home to buy?

4

I’m looking at the google home (mostly for the call santa feature… https://lifehacker.com/how-to-talk-to-santa-claus-with-your-amazon-echo-or-goo-1820805697) I’m looking at the mini chalk color… but sell me on why I should pay the extra and get a full size google home? (other than the 4 spinning lights)

We have 3 Alexa devices- 1 in the living room, 1 in my son’s room, 1 in my car… That’s part of my hesitation to getting into a different speaker ecosystem… plus we’re iOS users…
