Where these two actually differ

- We flag Non-stick coating (lid) degradation and shedding, Seal ring and gasket degradation and Electrical component moisture ingress and mold on the Instant Pot and not on the Instant Pot.
- The Instant Pot is Stainless steel pot with no nonstick coating where the Instant Pot is stainless steel inner pot, unspecified non-stick coating on lid, which is most of the difference in these two grades.
- The gap is 60 points, wide enough that this is not a close call, and the Instant Pot is the one to buy.
