Choosing the best cryptocurrency wallet will depend, first of all, on your budget: if you are looking for the most affordable options to store your Bitcoin (BTC) , Ethereum (ETH) and Dogecoin (DOGE), so for less than 100 euros you have very good options in Ledger Nano S Plus and Trezor Model One. If you are willing to spend a little more, jump to the higher-end models of both manufacturers without fear.
