Blockchain.info is having a lot of issues lately and I really recommend anyone using it to stop already , If you don't want to regret later maybe Its the best time to stop using it.
Possible alternatives : btc.com (If you want to stay with web wallets) , Electrum (desktop) , Multibit HD (desktop) , Paper wallets for long term and Nano Ledger S as a hardware wallet (It has multi coins support too)
well these are all tools and none of them are perfect.
any user needs to know the weaknesses and strength of each one of these tools before using them. for example using blockchain.info has all the bad things you already know but it also is an easy way for newer members to have a bitcoin wallet , also have it handy anywhere they are fast and easy.
electrum and multibit are SPV clients and SPV client is never perfect. there is the matter of trust, that you need to put in the servers you connect to so that they give you real information and not withholding anything. (there are good articles about weaknesses of SPV client online you can read)
and paper wallet is only good as long as you deposit only. spending it is going to be a long process of sweeping, spending and creating a new one to put the remainder in.
full node is the best option but it also has problems such as the big amount of disk space that it is going to take for blockchain. also the high amount of network traffic that it is going to need.
