I've been using the blockchain.info wallet for a few years now and didn't have any problems whatsoever, except for the fee oscillating.
You can get your private keys, various security options, has direct exchange,etc... the only thing that's missing is the support for segwit.
I am also using blockchain for a while now and it has really low fee when we compare it with its rival of coinbase wallet,and it also has more security options than coinsbase.So blockchain wallet can be considered as the alternatives for many wallets but I am wondering why the OP is looking for alternative to blockchain.info.
But I have seen that blochchain wallets more ofter faces bugs like can't send the bitcoin,so it may be a reason for him to search an another wallet.
I just found a wallet name called cryptonator multi coin wallet but I never tried it so if you want to try use it with you own risk.
