I have an instant pot and it's pretty good, but it's not the only cooking device you will ever need. The issue I have with it is that because it's a sealed pressure cooker, everything comes out a bit "boiled" looking/tasting. That's fine for chili or stew, but not so great for chicken.
That's fair. I might be preaching to the choir here, but something that might help is braising the meat in a small amount of liquid, rather than stewing it by covering it in liquid.
