Verdict

Both providers are practically level in our overall rating (4.6 to 4.7).

Ledger FlexOur Opinion

The sensible premium Ledger: clearly cheaper than the Stax with the same touch-based signing experience. If you want a bigger screen than the Nano series offers, this is currently the best compromise in Ledger's line-up.

OneKey Classic 1SOur Opinion

The price challenger from the open-source camp: a solid security set-up for little money. The brand and its ecosystem are younger than Ledger's or Trezor's, but if budget matters it deserves a look.
