Verdict
Both providers are practically level in our overall rating (4.7 to 4.6).
The mobile alternative to Tangem, with one real security advantage: its own display, so you verify transactions on the card itself. It is designed to be carried daily; for your main cold storage, a classic desktop device remains the safer choice.
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.
