My concern around a hardware-generated seed is the actual level of randomness. I haven't looked into anything specific, but for most hardware wallets the randomness seems to be computer-generated - as opposed to rolling dice, etc.
So, it's more about how much entropy the generated seed has. In my opinion, some hardware wallets really excel in this.
  • Hardware Wallets: They use special algorithms to create randomness (entropy) through cryptographic methods, making them secure against various risks. They often let you also add a 25th "word" with your own numbers or letters.
  • Dice: They give you randomness based on the physical environment (like the table material or forces applied).
I recommend checking out this article about the secure layer of the open-source Bitbox02 made in Switzerland. Big credit to these Cypherpunks! :)
