I own an Instant Pot and I wasn't impressed. The rice sticks unlike a real rice cooker and the pressure cooking was slow. I followed some normal pressure cooker recipes and I had to double or triple the time.
Rice doesn't stick only in rice cookers that don't have a non-stick interior pot. My parents have some older generation rice cookers that still work, and they have aluminum interior pots and the rice sticks to them.
The only problem is that the stuck rice doesn't burn a little at the bottom. That is the best part of the rice when mixed with soup.
