Best in all respects: coinbase.com, this kind of purse is easy to use so it's suitable for both novice and experienced people. You can swap to buy BTC, Ethereum, Litecoin ...
coinbase is not a wallet. it is an account where gives you some numbers in their database which are more like a promise of payment not real cryptocurrencies because you do not control the private keys so you do not have any control over the coins you store with them.
blockchain.info on the other hand gives you your private keys and you have full control over them.
to OP, have you tried using a desktop lightweight wallet like Electrum? it is so much better than a web wallet.
