Pressure cooker for tough meats, potting food
Pressure cookers are typically thicker metal than most camping pots so not ideal for backpacking obviously but for other types of camping like car camping, canoe, horse, ATV they may make sense because they cook stuff faster and thus use less fuel. This is especially true of items like beans (not instant) and wild game that is tough.

As a kid when we lived for months in very primitive places my mother would cook beans, rice and wild game in a pressure cooker mostly over a wood stove but occasionally used butane (which was scarce, flown in by small plane). One other advantage was that after she removed some meat, she could reheat it thus killing the bacteria and reseal the lid and sorta pot the meat with the beans and rice for a meal the next day. (We had no refrigeration.) After about the 3rd day the meat would get very stringy and lose almost all flavor. So we would REALLY be looking forward to a successful hunt or fishing trip, or be thinking about killing a chicken or duck from the village. Beans and rice with no meat gets really old after a week or two. I'm just sayin'.
