I have a ledger nano S and so does everyone I know IRL that is into cryptos (which aren't that many), it's probably the most used hardware wallet and probably the safest right next to Trezor, those two are the only ones I trust tbh... Ledger Nano X with their bluetooth function make me a little worried, having more ways to connect to the wallet probably decreases the security of the wallet, I need to get my hands on one to try it out and see for myself.
