I like the seed vault the most. Esp since you can hide it behind a separate login pin.

Other cool things: address explorer/verification, ability to scan qr for passphrase, multiple airgap options (qr, nfc, microsd), duress pins and decoy wallets, seed XOR.

Things I havent used but seem cool: ck bunker, keyboard emulator (for pw manager), physically destroying NFC and USB data.
