Blockchain is ok and has many features but there has been a few problems on the past that concerned me enough that i changed my online wallet.
I now have 7 different wallet apps on my phone and find Wallet32 good for a HD wallet but it doesn't have a option to sign a BTC address so that sux.
I have also used greenaddress and that is ok, maybe a bit slow sometimes.,Coinbase and Coinjar are good too but because you dont hold the private keys to these wallets then i only use them to buy/sell and reload my Coinjar swipe card.
Any coins i have are alway kept offline on a paper wallet that i make with a Mycelium entropy, so easy to use.
Because of my cold storage i almost always use Mycelium wallet now as it has everything i need and pairs great with my cold storage and will also now pair with Trezor.
I would say the Mycelium is the best wallet, noob friendly and got everything you need.
Whatever wallet you go with never leave more thn you can afford to loose online because anyone can get hacked., and also use 2fa always!
