I have chosen Ledger nano s, because for my taste it looks better than Trezor 
And do not have problem with it, correct device, could recommend it.
Ladger Nano S winning by public opinion and i am big fan of Ladger Nano hardware wallet because i using it few years ago until i didn't face any difficult issues it's security and other problems. This wallet good supporting new third party crypto-currency. Trezor is the second position in the peoples recommendations. And i think those two wallets is the most popular. And do not have problem with it, correct device, could recommend it.
