So in my opinion, hardware wallet is OK for a little amount, but for a larger amount, you should think it over again...
The seed is just a few words. Who says it has to be written down on something anyone can physically find? You can store the seed as a txt file in encrypted form anywhere in the world. Stick it on a few SD cards and tape them to a few different places.
Hardware wallets often also offer a 25th word to encrypt the seed. That's going to be rather easier to remember than the other 24.
