I am unhappy with Trezor’s attitude that just because their devices can be transparent/inspectable by anyone, they feel no obligation themselves to get their devices independently tested. For one example, they are not even considering seeking out FIDO Alliance certification for their security key app.
I also question their three-chip design, in comparison to Ledger’s approach to run everything inside its secure enclave. I don’t really see why their design would be a problem to be fair, but added complexity often causes trouble as a general rule.
In my draft I currently intend to recommend only Ledger as security keys, and recommend both Ledger and Trezor as crypto wallets in a new hardware wallet section.
