Pros and cons, side by side

Keystone 3 Pro

What works

Three secure element chips, against one on Ledger's and Trezor's flagship devices
A 4 inch touchscreen that shows full transaction detail, including decoded contract data
Fully air-gapped: signing happens over QR codes or microSD, never USB or Bluetooth
Fingerprint unlock and anti-tamper protection that wipes data if the case is opened
Dice-roll entropy, Shamir backup and BIP-129 multisig, a standard Keystone co-authored

What to watch

Not bitcoin-only, so multi-chain parsing code runs on the device
Keystone's shipping page claims worldwide delivery and then publishes a 56 country list
Air-gapped signing means scanning QR codes for every transaction, which is slower than plugging in a cable
A newer brand with a shorter public track record than Ledger or Trezor

Ledger Nano S Plus

What works

Cheapest current Ledger at $59 on Ledger's own store
Same ST33K1M5 secure element, certified to CC EAL6+, as the $399 Stax
Far more coin app storage than the original Nano S it replaced
No Bluetooth and no battery, so there is no radio attack surface and nothing to wear out

What to watch

No iOS support: Ledger's system requirements list Windows, macOS, Ubuntu and Android only
Cable only, so you cannot sign from a phone without plugging in
The 128 x 64 pixel screen turns checking a long address into a multi step scroll
Closed source firmware, unlike Trezor and BitBox
