This sounds like trezor devices are more secured. Thats not true. Both, the trezor and ledger nano, are on the same level security wise.
Trezor even had a bug in one of the last firmwares where an attacker with physical access to the device could have read out the seed, in some circumstances,
because it was dumped to the RAM unencrypted while resetting. You can't have 100% security. Both are fine.
Is this the case of the news editor guy where he paid someone to build him something to hack it? I remember them saying that if he had a passphrase, it was game over.
Honestly at the end of the day, nothing is 100% proof. You can have FIAT currency in your bank vault, and through some intricate ways, that can be stolen too. you bank account can be hacked, your wallet can be stolen...
can't make it world proof. You just do your best.
