Buy a Ledger Nano S. Very nice, secure and easy to use hardware wallet.

If you can't afford it, as software wallets I would always advice to use the official ones from each project.

If you prefer to have a multi-coin wallet, then I would say Exodus is a nice choice. It allows you to export the private keys and their interface is awesome.

Soon we will have many interesting projects with promising wallets like ETHOS and Bread.
