Main Difference: Functions, Cooking Versatility, and Smart Features
The key difference between EG201 and FG551 lies in their cooking versatility, smart features, and capacity. EG201 is compact and ideal for small households, while FG551 offers advanced grilling, air frying, and precise doneness control for larger meals.
Overview of Ninja EG201 Air Fryer
The EG201 is a 4-quart indoor cooking appliance with 6-in-1 functionality: grill, air fry, roast, bake, broil, and dehydrate. Its compact size and stainless steel build make it perfect for limited counter space. During testing, it handled weeknight dinners for 2–3 people efficiently. Fries, roasted veggies, and small baked dishes came out evenly cooked every time.

Overview of Ninja FG551 Indoor Grill
The FG551 Foodi Smart XL Grill is an all-in-one appliance with advanced grilling and air frying capabilities. Using 500 °F cyclonic grilling technology, it delivers char-grilled flavor indoors. Its Smart Cook System with built-in thermometer ensures meat reaches the perfect internal temperature. During testing, we cooked 4 ribeye steaks simultaneously, and the thermometer gave consistent medium-rare results — a level of precision EG201 couldn’t match.

Cooking Functions & Versatility Compared
Both devices offer similar core functions: grill, air fry, roast, bake, broil, and dehydrate. The FG551, however, adds advanced smart features and higher grilling power, enabling precision cooking for larger meals.
