If you prioritize security, then the answer is wallet hardware, because the wallet can be removed from the internet connection
but if you put simple in use, then the answer is the wallet software
Any wallet 'can be removed from the internet'. A wallet itself is just a (either hardware- or software-) manager for your private-/public- keypairs.
An internet connection is (only) necessary if you want to broadcast your transaction (relay it to other nodes).
Software wallets are not simplier in use. This completely depends on the User interface.
The UI of electrum (software wallet) can be kind of irritating for new user, where the UI of the nano s (hardware wallet) application seems pretty 'clear' and 'intuitive'.
Yep, for example, i would like to hold my BTC in wallet.
What example of hard wallet you can recommend?
Didn't bother to read the first reply?
The most reputable hardware wallets are made by
Ledger and
Trezor.
