For now I'm using MEW and Eidoo for my Ethereum wallet. Both of these wallets are good, and also have advantages. I think Eidoo is a wallet that has a very good transfer speed while MEW is Eth's first wallet I know. And as long as I use these two wallets, I haven't got any problems. but from these two Ethereum wallets, I would recommend choosing Myetherwallet or MEW for your Ethereum wallet.
