The BitBox02 offers several advantages, I'm not as familiar with Jade.

- Compact wallet design with a large, easy-to-read screen

- Packed with security features, including two secure chips and open-source software

- Option for a Bitcoin-only or a multi-currency wallet

- Compared to similar hardware wallets, the price is reasonable

Can be backed up on microSD cards

One cool feature of BitBox 02 bitcoin only is that you can use an optional passphrase on top of your existing seed: if you leave it blank you get access to "main wallet", but for each different passphrase you derive a different wallet from the main seed, and this passphrase never gets memorized on the device.

This mean that you can safely store btc on a derived wallet as your "secret stash", and if in a bad situation (fiscal control or theft attemp) you can input a different passphrase to show a totally different balance.

You should store the seed and the passphrase in a separate place to be completely safe.
