Verdict
Both providers are practically level in our overall rating (4.6 to 4.7).
Alongside Trezor's Bitcoin-only devices, this is the first choice for Bitcoin purists in Europe – Swiss build quality, open source and a minimal codebase.
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.
