I have not used either of them but I did catch a commercial about the Philips Airfryer. It looks amazing! From what they showed, you can do just about anything with only a tablespoon of oil. You can do grilled cheese, potato chips, french fries, fried chicken, to chocolate brownies, frittatas, even roasted meats and vegetables. The next appliance I get will probably be this one!
