The best wallet that you can use this hardware wallet, Trézor is in my opinion the best and most functional wallet. It also has a built-in password manager feature.
What features make the Trezor superior to the Ledger?
Imho it's only his personal preference and isn't related to any safety-critical features.
I prefer the Ledger Nano S with its handy design and the amount of supported currencies (and the price).
Never had any problems and in terms of security it shouldn't really matter if you choose the Trezor or the Ledger Nano S.
