I've used two brands recently.
Foundation Passport is nice. If you only need cold storage for yourself, it's great. Probably a great solution overall. Especially if you want to scan QR codes, it is excellent.
Coldcard Q. This is my favorite because it fully supports BIP-85, which are child seeds derived from the master seed. The BIP-85 feature supports exporting as many xpubs as you wish, for watch-only wallets. This is great if you are being an Uncle Jim to members of your family. All the child seeds are backed up in the Coldcard. The QR scanner is not compatible with most software wallets though. So I transfer psbt's via sd card, which always works.
