Agree with all the people here, MyEthWallet is really the easiest to use one.
However, i don't recommend you to use web-based wallets at all, the reasons are obvious

I prefer Exodus, imo its the easiest one to use on a desktop platform.
Web wallets are fine as long as you control your private keys, if you use a web wallet in combination with a hardware wallet like trezor or ledger nano s you will be very safe.
Web wallets are extremely dangerous when they hold the private keys for you.
In the case of myetherwallet when using it with a seed file password, and a trezor or a ledger nano s it is a very secure environment.
