Which is better for a family of four?

The Fullwill 6qt. A 4-quart pot is cramped for four servings plus leftovers, and the 6-quart size handles a whole chicken or a big batch of chili.

Which is better for one person?

The Instant Pot RIO Mini 4qt. Its 4-quart capacity is right for one or two people, and the compact footprint and front-facing steam release are easier in a small kitchen.

Do both have a slow cooker function?
