In both cases ideally, you would still have a human-readable backup of your keys.

With a ColdCard you are trusting "source viewable" but not Open Source software.

With a seedsigner you are trusting open source software, and you can buy the general purpose components to create without putting your contact info on a list showing you bought Bitcoin related stuff. Better OPSEC.

Perhaps the way to compensate is using seed QR as part of a multisig wallet to eliminate a single point of failure.

I think that's a great thought. Or a passphrase could do the trick.
