BITKEY IS MUCH EASIER TO USE AND BETTER BUILD QUALITY.
Discussion
Jade has a screen tho!
JADE IS LESS SECURE THAN COLDCARD AND HARDER TO USE THAN BITKEY.
WOULD NEVER USE IT PERSONALLY.
Jade is only "less secure" to a Coldcard if the Coldcard is part of a multi-sig setup made up of other geographically diverse hardware wallets. Otherwise if it's a single sig Coldcard it's more secure assuming the use of the 2of2 or 2of3 account types in Blockstream Wallet. It's cool if you dig Coldcards, but don't spread misinformation.
If you're storing the seed in the device, sure. But simply using it as a temporary airgapped signer, how is it less secure?
