Blockchain.info is the best wallet
I use blockchain.info, never found error. I think you must trying wallet from blockchain.info, and then i have private key , so if any problem my bitcoin not lose.
Obviously 90% will suggest to use blockchain.info as it is official version and our cryptocurrency is totally safe on their hand. If you still want to use 3rd party wallet is upto your thinking, I don't use any party wallet so I guarantee what they could do to your account 
Blockchain.info IS NOT THE OFFICIAL WALLET!!! Most people will in fact NOT RECOMMEND THAT YOU USE THEIR WALLET. Their service has had multiple security issues and vulnerabilities in the past. Furthermore, they ARE a third party wallet. You do not control your Bitcoin if you store it with them; they do. Should their service shutdown, you will lose all access to your Bitcoin.Blockchain.info IS A SERVICE, NOT THE BLOCKCHAIN. THEY ARE NOTHING OFFICIAL.
Yes it's a bullshit situation when they named themselves BLOCKCHAIN, now every newbie will be confused about it.
However you can still use them as a MULTISIG system.
Make a 2/3 multisig wallet, keep 2 keys on paper offline (where 1 key is stored for longterm, and 1 key is for immediate use),and 1 key at blockchain.info's wallet.
Then you just use the immediate paper key and the blockchain wallet to authenticate a transaction.
If blockchain.info gets hacked, then you create another multisig. If you forget 1 paper key or the blockchain login, then you use the other paper key as the 2nd key.
