If you mean the ones that come built into the stoves now, they definitely are. Air Fryers will make your food brown and crispy and cook food evenly without drying it out.

An average dishwasher cycle lasts between  1.5 – 4 hours. Some units now have a quick cycle, which is 60 minutes. It really depends on the cycle you choose.

If you want to know my favorite, I really like the Profile or Café line. The Café with the French door is one of the best on the market.
