I'd personally say air-gapped wallets set up correctly are safer than hardware wallets,
I agree with this, with the caveat being a person must know what they're doing.
but I don't think any person has lost any coins over either so far, so you should be safe no matter which way you go.
Actually, here is a story of a guy who lost $30K using a Trezor because he forgot his PIN. The story has a happy ending as a hack was able to bypass that lock, but he could have definitely lost it.
