That does not mean any other hardware wallet database is perfect, anyone of the can be hacked at any time. The best is to find a way you can purchase hardware wallet in a way information you provide company can be linked to your real identity. Do not be surprised if you heard the data of another hardware company is leaked tomorrow, try to protect you identity yourself.

Only what I do not like Ledger Nano is because it is not completely open source, its secure element which generates and store the seed phrase is close source, while many reputed members are still recommending the wallet. That is the fact that makes me prefer Trezor which is completely open source but which should be used with passphrase to make the possible physical attack not to be able to reveal your keys and addresses if possible the hardware wallet was stolen.

But, you are not wrong, more hardware wallet are recommendable but people do recommended Trezor and Ledger Nano because they are the most used and more tested for vulnerabilities.
