The catch
Instant Pot RIO 6QT Black
Sous vide is absent from the seven cooking functions listed for RIO.
Side by side
Instant Pot RIO 6QT vs Duo Plus WhisperQuiet 6QT: Whisper brings sous vide and written guidance and doesn’t enlarge the batch
Quick verdict
RIO 6QT is right if you like its simpler progress indicator and have no need for the Plus message bar. Duo Plus WhisperQuiet is right if you will use sous vide or want written guidance on cooking and the lid. Anti-spin stainless inserts and six-quart nominal capacity are already shared by both.
Before you buy
Why, and what it costs you
The interface difference worth caring about is written prompts
RIO has a cooking progress indicator. Duo Plus adds a message bar showing cooking instructions and lid-status messages. An adult coming back after an interruption may get more from words that explain the stage than from an extra preset. Still, the words do not prove the food is finished, and they never make opening a pressurized lid acceptable.
Where this comes from

The catch

Instant Pot RIO 6QT: A cooking progress indicator. Instant Pot Duo Plus WhisperQuiet 6QT: A progress bar plus a message bar that carries cooking instructions.
Sous vide is a reason of its own to choose the Plus
A sous-vide program is in the Plus manual, and RIO’s seven listed functions leave it out. Households that regularly follow suitable water-bath recipes could find that difference matters apart from the screen. When dinner is mostly pressure-cooked dishes, both already handle that main job. We draw no conclusion about cooking quality or food safety from the extra mode.

Extra controls do not turn it into a larger meal-prep pot
Each model is nominally a six-quart cooker with an anti-spin stainless insert. If a recipe goes beyond RIO’s appropriate fill limit, switching to Duo Plus does not fix that. Taking the lid apart and cleaning the valve is still required too. When batch size or cleanup is your main annoyance, deal with that before paying for more interface features.

Option A
