I haven't used a Passport, but heard it's really good with QRs.

Jade was amazing at reading QRs, but due to its small screen size, reading QRs back from it was a challenge.

I used the same hand-drawn seed that was recognizable by Jade in a matter of seconds, but CC Q couldn't recognize it. I think it's due to a difference in standards, rather than a shortcoming in CC Q's scanning ability.

CC Q is good at reading, but doens't do a good job of producing a scannable QR for signing transactions and this is despite its bigger screen. It is only a small improvement over Jade (classic) when it comes to transaction signing.
