This is a pressure cooker with a teflon lined pot. The Instant Pots all have stainless steel pots which will hold up to time better. The 6 qt. insignia does not start counting minutes after the cooking has finished. I like being able to see how much time has lapsed so i can know when to release the steam. If I was going to just buy one, I would buy the Instant Pot Duo or the Instant Pot Vista when they are on sale. But this is a great 2nd one to have. (One for rice, the other for roast; one for yogurt the other for soup, etc.) Accessories are interchangeable with instant Pot.
