My partner got an Instant pot but I don't like the meat that is made in it. Maybe it's overcooked? Tomato-based ground meat (e.g. ground lamb) sauces are tolerable.
I generally prefer my meat fried (seared) in a cast iron pan and finished in an oven (if necessary, e.g. a big piece of beef).
The thing about pressure cookers is that they are basically a time saving device; what you get out of them is similar [1] result to what a long, slow cook in the oven would have been. They cook at higher heat without boiling.
You aren't going to roast in them, or anything like it. But a stew that would have taken 3+ hours can be done in less than 1. Typically you should be using different cuts of meat for these applications.
[1] the big caveat is you don't lose moisture, so liquid amounts all need to be adjusted
I personally add fresh seasoning (including salt and paper) and olive oil at the end, this way you maximize the taste of the seasoning and olive oil. Same for garlic.
I'd only recommend the Instant Pot for fatty, braise-friendly meats. It can be difficult to get lean meats/fishes right because of how intensely it's cooking.
