Whatever wallet may come into existence one after another my all time favorite is blockchain.info because it's official and I have full trust on it. And on any third party wallet I can't trust them.
I also use blockchain.info wallet rather than any wallet because it doesn't takes a lot of time when i transfer money because i received bitcoin instantly even there is no confirmations yet. I think it is because it is official and it is the main source of the other wallet so there is no problem in blockchain unlike other online wallet.
