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 most consistent choice for bitcoiners: the same hardware as our Safe 5 test winner, but with minimal firmware. If you only hold BTC, this cuts your exposure without costing you anything in usability.
