The Instant Pot made “one pot does everything” a category promise: pressure cook, slow cook, make rice, steam, saute, all from one machine. The older setup is two dedicated appliances: a rice cooker that only makes rice and a slow cooker that only slow-cooks. This post compares the one-pot route against the two-appliance route on verified models and dated prices, and ends with per-case verdicts.

What each route actually is

A multi-cooker is an electric pressure cooker with extra modes. The verified 6-quart models here list pressure cook, slow cook, rice, steam, saute, and keep warm among their modes, plus extras like sous vide and yogurt on the higher picks. The feature no separate rice cooker or slow cooker can match is pressure: none of the dedicated appliances build pressure, so none of them cook dried beans or a tough cut in under an hour the way a pressure cooker does.

The separate route in this comparison is an Aroma 6-cup rice cooker (ARC-763C) and a Crock-Pot 7-quart manual slow cooker. Neither does anything outside its name. Their case against the multi-cooker is price arithmetic and a second point the spec sheets don’t mention: two appliances can run two different jobs at the same time. A multi-cooker cooks one thing at a time, so rice and a slow-cooked stew together mean two pots regardless.

The four models, on published figures

The price math, with dates attached

The separate stack costs $30 (Aroma, read Oct 7) plus $59.99 (Crock-Pot, Best Buy, read Oct 14): $89.99 for both appliances. The cheapest verified 6-quart multi-cooker is the Instant Pot Rio at $109.99 (read Oct 10). The stack undercuts the multi-cooker by about $20, and each appliance is simpler: one dial on the slow cooker, one button set on the rice cooker.

The gap closes when the extra modes matter. The Duo Plus at $139.99 adds sous vide and a quiet steam release over the Rio; no combination of the Aroma and Crock-Pot adds pressure cooking, so a cook who wants pressure is comparing against $109.99 minimum, not against zero.

The job neither side does well

Slow cooking is where the two routes are closest, and the honest answer is that both do it. The Crock-Pot’s slow cook is its entire job: a manual dial, high and low, warm to hold. The Instant Pot’s slow cook is one of several modes inside a pressure vessel. We have no published test data comparing the two slow-cook results, so this post does not rank them; the difference that is verifiable is the controls. A dedicated slow cooker has one job and three dial positions. A multi-cooker’s slow mode sits behind buttons and a display, and switching modes means learning the interface.

Rice is the same story in reverse. The Aroma’s only job is rice. The Instant Pot lists a rice mode among its 7 to 9 functions. Which makes better rice is not something the published specs can settle, so we don’t settle it. What the specs do settle: the Aroma’s $30 price is the cheapest rice-cooking entry here, and the rice cooker keeps cooking rice even when the multi-cooker is busy with something else.

Verdicts by case

Buy the multi-cooker if pressure cooking is the point. Dried beans, stock from bones, a pork shoulder in under an hour: nothing in the separate stack builds pressure, so nothing in it replaces this. The Rio at $109.99 is the verified floor for a 6-quart pressure platform with a published wattage.

Buy the separate stack if rice and slow cooking run together. $89.99 buys both appliances, and each one works while the other is busy. A household that makes rice most days and slow-cooks stews on weekends gets two machines for less than one multi-cooker, with simpler controls on both.

Consider the Duo Plus if sous vide or quiet release matters. At $139.99 it is the only model here with sous vide and a published quiet steam release. If those two features never get used, the Rio does the same core jobs for $30 less.

Skip the whole comparison if counter space is the constraint. One appliance versus two is a footprint question, and none of the pages we opened published complete exterior dimensions for all four models, so this post does not pretend the footprint math exists. Measure your counter before either purchase.

How we compared

Every spec above comes from a manufacturer or retailer page we opened ourselves: instantpot.com for the two multi-cookers, aromaco.com for the rice cooker, crock-pot.com for the slow cooker (model and spec verification), and Best Buy for the slow cooker’s price read. Wattage is printed only where a page published it: the two Instant Pots at 1,000 W, the Aroma at 300 W. The Crock-Pot’s spec block lists no wattage, and the brand’s own Q&A gives two conflicting figures, so the table prints none instead of borrowing a number from a marketplace spec table. Prices are stamped with the retailer and the date we read them. We have no model-confirmed Amazon ASINs for these four exact models, so this post carries no buy buttons; when a model-ASIN link is confirmed, it appears here.
