I got a Ninja 11 in 1. It’s does a bunch of stuff including air frying, pressure, cooking, slow cooking etc in general it’s great and I get good results with it but it’s huge. I’d definitely look at something like this if I were you and you’re open to getting rid of some kitchen gadgets to combine into one. That being said I use the pressure cooker and slow cooker bits a bunch and only dabble in air frying as an alternative to deep frying and for speeding up roasting things. Most common things in the air fryer are, home made fries, wings, quick roast potatoes, home made chicken tenders and breaded fish fillets I should really expand the repertoire here but it’s quick and to some extent fire and forget for these basics
I have the Foodi, the one that doesn't need a separate lid. I've had it for around 3 years I think. It's a big chonky machine, but I love it and recommend it to everyone. I use it more than the hob at this point! The modes I use the most are air frying, pressure cooking, sear/saute and bake. The stream to air fry mode is also great for making a whole chicken! My boyfriend has been using it when at my place and likes it so much he's going to replace the Instant Pot he has at his place with a Foodi because he wants an air fryer and it's much nicer to have it all in one. The one downside it has compared to a normal air fryer is that the basket is not very big, and it's also quite noisy compared to dedicated air fryers. Personally, the trade off is worth it for me. Happy to answer any more specific questions!
Decent for the price with okay warranties. I have a Ninja Foodi air fryer/pressure cooker/slow cooker/all in one jawn that sits on my counter and get's used like 3 times a week minimum. It's one of my favorite appliances in my kitchen because I primarily use it as an air fryer but it can also be a second slow cooker for when I'm making a huge meal. The steamer function on it is pretty tight as well, boa buns come out perfect from it. The coffee makers are also decent but I wouldn't use them for high end things like espresso. A simple ninja drip coffee machine will be just fine though. Blenders again are decent but ill not outperform something like a Vitamix or more high end. Knives? The knife block is okay but I hate pull through sharpening systems and am generally against buying sets as a whole. You only need a few good knives. Generally Ninja makes decent things that will do the thing they are advertised to do. They won't do them exceptionally well as compared to products that specialize in said task but they aren't poor quality items either.
I love love my ninja foodi. It changed my life. The one with the pressure cook lid is all you need.
I have the combo blender / food processor, and the combo air fryer / pressure cooker, and I rate them both incredibly highly and use them every day. I also found their customer service to be great. Overall my advice would be to only get machines you know you would use but I personally like devices that can do a couple of things to earn their keep. One day I’ll crack and buy the Creami, but not yet.
You won't find one - I have had 4 different air fryers, the first was a cheap Phillips, second was a ninja with 2 draws, the third was a better Phillips and the 4th is now an all in one with ninja with pressure cooker .... They all do the same thing, cook my food faster and better than an oven does. Only difference was the size
