I've got the ninja 11 in 1 which does pressure cooking and air frying (plus various other stuff like steaming and air frying simultaneously, slow cooking and grill which I use a surprising amount).
It can cook rice but, as others have said, you need to cook a lot of rice to do it.
I prefer the all in one hinged lid as you don't need the storage space for another lid (they're big) and you don't need somewhere to put it down halfway through cooking. Downsides are it won't fit on a worktop with cabinets above and, if you're pressure cooking, it's wise to give the seal a quick clean (30 seconds of a job) as otherwise it may not seal and won't get up to pressure.
You can often get them cheap on Amazon warehouse
My latest kitchen wish list includes a rice cooker, and air fryer, and lately a pressure cooker.
Normally, I'm all about single purpose appliances - do one thing, do it well.
Except cupboard / surface space would then be a problem.
So: all-in-one shenanigans (and if so, which one) or curb my window shopping and stick to one of three (again, if so, which one).
