Ledger Stax and Ledger Flex both use a touch-screen direction, but they feel different in daily use. Stax is easier to understand as the larger-screen option, while Flex is easier to understand as the more compact touch-screen option. The right fit depends on reading comfort, handling style, and where the device will usually be used.

Choose by the main comfort factor

Pick Stax if a larger display helps you read menus and device prompts more comfortably.
Pick Flex if compact handling matters more than screen size.
Use the same setup discipline for both: device screen first, app screen second.
