I would recommend not to trust a chip/device alone, things can go wrong in a lot of ways. A physical backup is important. Also, a passphrase can save you in case someone sees the seed.
Of course, I even have a topic about this.

Unfortunately, keeping a QR code with me and making sure nobody takes a picture of it, I don't lose it, ... does not fit my usage model for such a device at the moment.
I understand what you mean, but someone could take a picture of your regular seed words for any other bitcoin wallet Wink
I don't need to carry around my seed phrase backups, though. They are in safe locations.
Meanwhile a hardware wallet with secure element can also be left in a less secure location where it is quickly and easily accessible.

Krux is basically an airgapped computer that lets you easily import a cold / offline / paper wallet.
The necessity to protect the (cleartext) seed QR is a pretty huge downside of this system. You can't even know if someone copied it, since you always carry it around in clear text.
While a quick picture of the QR gives the attacker full access, as well as the ability to stay unnoticed, hacking a Passport (or similar) requires it to be gone for hours (to attempt an intensive hardware attack), which should be much more likely for you to notice.
