I fell in love with my Instant Pot Duo last year but as my tiny humans have begun to eat more I felt it was time to upgrade to the larger pot our Instant Pot Duo was the 6 quart and we wanted the bigger 8 quart but since we had gotten ours there were a few upgraded models out so we did some research on them. This comparison chart is helpful at seeing the differences in the models. We decided on the 8 quart Ultra 80 and so far could not be happier. I love that the lid works a bit better and it doesn’t struggle to come to pressure which our duo did occasionally. The knob feature is really nice and I love the look of it.
