Is a single-basket or dual-basket air fryer better?

Across the reviewers and r/airfryer threads we read, single-basket models tend to crisp more evenly and are easier to clean, while dual-basket units shine when you need to finish a main and a side at the same time. Several community posts surfaced one consistent complaint about dual-basket designs: cooking with only one zone can feel wasteful, and some owners said they'd have preferred one larger basket.
