You cannot compare it with a hardware wallet like trezor. Hardware wallets provide a much higher level of security that online or desktop wallets. But if you are going to store coins that are not not yet supported by Trezor, better follow the official wallets for the time being and then add them to Trezor once they open their support for these coins.

You should never compromise the moving of coins to less secure wallets just because you dont know the advantages of the hardware wallets. But it also helps to keep your devices clean and updated to prevent attacks from hackers.
