Agreed. I found that stews/soups especially had less flavor absorption when pressure cooked versus slow cooked. Plus the instant pot slow cooker function sucks, it barely goes to a boil, and if you use the sear function to get a bit more heat you are limited to 30 minutes.I bought into the whole instant pot hype. It's actually pretty awesome that you can do things like braised short ribs in like 45min as opposed to the 3 hour dutch oven method. I'd still however opt for doing it the low and slow method in a dutch oven whenever I have the time. IMHO what you give up for the convenience of faster cooking time you lose in flavor absorption. Same recipe will almost always be better done the long way. But it's really nice to come home from work and have short ribs on the table before 9pm.
That said, for cooking beans and making chicken and beef broth, it’s friggin amazing.
