Even if you use hardware wallet there's no guarantee that your funds won't be in danger, such as when your hardware wallet is broken or have some bug. Paper wallet is safer than hardware wallet as long as you can back up correctly.
If your hardware wallet breaks you can get a new one and import your 24 word seed phrase and restore it. Your crypto wont be lost. Or import it to a different wallet that supports this function.
Paper wallets are good for long term holding but they are not very handy if you need to make a transaction every now and then. Also, they are easier to destroy physically, water, fire, tearing etc. My point is, nothing is 100% safe if you are not using, storing it properly.
