What are the differences between convection ovens and air fryers in terms of cooking methods and results?

Convection ovens use a fan to circulate hot air, cooking food evenly and quickly. Air fryers also circulate hot air but at a higher speed, resulting in crispier and faster-cooked food. Convection ovens are better for larger quantities and a variety of dishes, while air fryers are more compact and specialize in crispy, fried-like results.
