Pros and cons, side by side

Blockstream Jade

What works

Bitcoin only, with both firmware and hardware published as open source
Three tiers from $79 to $149 sharing one firmware and one security model
Genuine Check attestation lets you verify the device was actually made by Blockstream
Jade Plus signs fully air-gapped over QR codes and reads an SD card
Blockstream fixed the DARKNAVY report in three weeks and published a full public disclosure

What to watch

No certified secure element, which is a deliberate tradeoff but still a difference from Ledger, Trezor and BitBox
Firmware 1.0.24 through 1.0.36 carried a stack overflow that a compromised host could use to crash the device, and 1.0.35 and earlier could allow limited code execution
Jade Core has no camera, so air-gapped QR signing needs the Plus
Free international shipping is advertised with no country list behind it, and you may owe import fees

Ledger Flex

What works

A 2.8 inch E Ink touchscreen at 480 x 600 pixels, more pixels than the larger and dearer Stax screen
Same ST33K1M5 secure element, certified to CC EAL6+, as the $399 Stax
USB-C, Bluetooth and NFC, so it works with an iPhone as well as a desktop
A Ledger Recovery Key is included in the box, so your seed backup is not only on paper

What to watch

$249 is more than four times the $59 Nano S Plus for the same certified secure element
Closed source firmware, unlike Trezor and BitBox
Plastic body with a Gorilla Glass front, where the Stax uses aluminum with stacking magnets
