There are a lot of different types of a wallets, each different type offers different benefits and drawbacks. So to ask which one is the "best" won't get you a good answer. There's hardly such thing a single "best" wallet. It depends on balance size, your use for bitcoin, your interest in level of management of your wallets (do you want to be your own bank), and your personal threshold for security.

Instead of asking us here, check out this site to help you choose your wallet: https://bitcoin.org/en/choose-your-wallet

There's more information out there on each, but this will help you narrow down the choices from the universe of options.

One last thing, there is one "wallet" that's paying interest on deposits. I put wallet in quotes because it actually started as a bitcoin faucet, so no one thinks of it as a wallet. But you can deposit your coins to this faucet and they will pay interest on your balance, daily. The interest is at 4% annually...so better than what's available in the fiat world. PM me if you want more details.
