How they differ in real use
Built from our multi cookers scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Instant Pot Duo Plus 9-in-1 and the Cosori 6.0-Quart Electric Pressure Cooker made our Top 5 Multi-Cookers & Instant Pots, at #1 (best overall) and #5 (best budget). The pressure cooker that started the revolution: 9 functions, proven reliability, and the largest recipe community. The safe bet. The budget pick now that the Crock-Pot Express is no longer sold on Amazon. America's Test Kitchen names the Cosori 6.0-Quart its Best Buy after it excelled at both pressure cooking and slow cooking, and it matches the Duo Plus on the basics: high and low pressure, slow cook, rice, steam, sauté and sous vide. It also carries a 2-year warranty and costs the least here. It ranks last because reviewers found it slow to come up to pressure, it lacks the Breville's automatic steam release, and its dark nonstick pot makes browning harder to judge.
