If you go to the Passphrase option, can you switch between letters instantly as in there is no delay between the button pushes? I do not seem to be able to switch between more than one to two characters per second.
I don't know because I never used passphrase option in ledger wallet and I don't like it's connection with pin code.
Unfortunately however, as far as rumors go, I heard Trezor's upcoming product will also feature a closed source chip which makes me wonder how many alternatives we will really be left with in the future.
I think that your information is wrong, Trezor won't release their new hardware wallet device before end of 2022, and they are working on their own Open Source secure element with
Tropic Square.
In
latest interview they said that they will sell this secure elements to anyone who want's to buy them, including other hardware wallet manufacturers.
