Hardware wallets are primarily manufactured by the two major firms, ledger and trezor. To compare the ledger nano s wallet to trezor, I'd like to compare the manufacturer with trezor, which, while trezor has been in the business for a long time and ledger only joined in 2014, there are two primary rivals and I know individuals who really believe in the security of ledger wallets.
Working with the ledger nano s is quite easy, and it resembles a flash memory, which I believe is a benefit that lowers the likelihood of its physical item being stolen (because thieves may not recognise that this is not a flash memory)
