I like my ledger nano s, but basically any ledger and trezor products and safe and easy to use. Combination of hardware wallets and safe back up offline storage will make you sleep fine.
Well each and every wallet in bitcoin is the best you can use it easily and very satisfyingly, you are right that having the backup system will reduce your tension about hacking and it will give you more profit and will have your bitcoin safe, Nano is the good wallet said to be hard ware wallet but mate I like blockchain for me, I prefer to sue blockchain as it is very easy and good to have for long time you will not be worry about the price of bitcoin increasing or decreasing, you will hold without any worry.
