By far blockchain.info is my favourite. It's the most complete wallet on the net. Even coinbase's wallet isn't that good. I do hope they will launch a stable version soon though.
Yeah, Blockchain.info is the best online wallet I have used, I have been using BC for over 3 years haven't had any problems yet. 
How about localbitcoin? Have been using it and no a problem for me yet, can buy and sell with ur bank.
Do you have access or control over your private keys on localbitcoin? I think not, You should consider switching your wallet where you have full access over your wallet.
