Which is better for a family of four?

The Foodi 8-qt. Its 8 quarts and two baskets let you cook a main and a side at once. The 4-quart holds about 2 lbs of fries, which is tight for four people.

Is the Foodi 8-qt worth the extra $50?

Yes if you often cook two foods at once or need the larger capacity. If you mostly reheat and fry single portions, the 4-quart does the job for less.

Which one gets food crispier?

The Foodi 8-qt reaches 450°F versus 400°F on the 4-quart, so it browns and crisps more at the top end. Both use convection heat.

Can the 4-quart dehydrate?

Yes. Its range starts at 105°F, low enough for dehydrating. The Foodi's listed specs top out at 450°F with no dehydrate range stated.

Which takes up less counter space?

The 4-quart, at 11 inches wide and 11 lbs. The Foodi is 15.63 inches wide, so measure your counter before buying.

Neither maker publishes a lifespan figure. Both are Ninja units with similar wattage; the 4-quart has fewer moving parts and one basket to wear out.
