Foundation Passport vs Keystone
Two hardware wallets with different architectures: Keystone works air-gapped. Foundation Passport is Bitcoin-only (minimal attack surface), Keystone is multi-asset. On code, Foundation Passport is fully open-source and auditable, the other is not: if sovereignty matters to you, that weighs a lot. On price Keystone wins: €150 vs €383. The right wallet is the one you will actually use: assess your flow first (holding vs frequent use), then the spec sheet.
