Trezor or paper wallet with more than one backups is enough.
I do not recommend paper wallet. OP is asking for a wallet that will support multiple currency, not only Bitcoin or Ethereum.
I am curious to know what misinformation about Ledger? The only thing that happened with the Ledger website is a data leak. It doesn't relate to the Ledger device, so the device still secure. I have been using Ledger for a long time and hadn't faced any issue yet. Database of Ledger website wouldn't harm you, because wallet seed wouldn't be pre-generated. This means no one has access to your Ledger wallet. For more security, create a seed for the first time after receiving the device and reset it by entering the wrong password 3 times. Then create another seed and write it in a safe place. So, there is no doubt that the seed was pre-generated. Any wallet wouldn't save your assets if you can't save the wallet credential. This means you have to stay away from a possible attack like phishing websites. Always try to verify any updates from the official websites. Keep in mind, you should need to buy a hardware wallet from the official site/store.
