In my opinion the blockchain is best then anyone wallet because blockchain is official wallet for the bitcoin .
But here no doubt that there are many wallets which are proving the blockchain with less facilities because many of the wallets are having best feature than blockchain .
Here my best wallet is myscellium and zebpay and coinbase .
But here if you are using coinbase then you should be careful that you shouldn't have the btcjam account with the same email I'd , because if your btcjam account is hacked by anyone then probably he can steal all of your bitcoin  . Since I never came in this type of problem but recently one of my friend said the same words for coinbase .
For newbie coinbase is better charge free .
