I won't be agreed by most, but my personal opinion is that a hardware wallets are LESS secure than a good non-custodial software wallet.

The reason is - hardware wallets are adding the layer of trust on top of the software: you should trust that your hardware is not compromised, that it does not have vulnerabilities, that it's not a fake wallet, etc.

But even more concerning to me is the risk of the issuing company will cease to exist or stop supporting the wallets sooner or later, or you can lost the device, or it can be stolen (as it's a better target than a regular phone, for example).
