- Blockchain (is it for ETH too?)
Yes blockchain.info is already accepting ETH and they have a wallet for it already so you can count them as your choice.
Is there any other wallet I should try?
You can use MEW (myetherwallet.com) for your own convenience if you just want to hold ETH.
And what's the differences among them?
Others does have other altcoins to hold/accept and MEW only focus with ETH and ERC20 tokens.
