i would choose for the blockchain all the way because it has a good future and it will be more popular than ever.
I already think its the most used wallet because its safe and does have the nice options other wallets also have that are not so good secured.
-Can't sign/verify messages at the moment.
-Auto updates your wallet without any notifications.
-Doesn't allow you to set custom fees,has control over your transactions.
-Wouldn't be surprised if my account is locked out of violation of their terms.
-Doesn't believe in providing options to back-up the private keys or letting users know how important it is.
-Still its the best "bitcoin" wallet ? I don't think so..
