If you plan for long term holding, Electrum for both PC and mobile will do the job. You will hold your private keys here so rest assured that your coins is safe and it will just lose via human error.
If you will do some regular used of your bitcoins or making withdrawals into fiat, search for your local exchangers there with good reputation since it's more way easy to access than to use international exchangers like Coinbase , XAPO etc to deposit and withdraw bitcoin.
I used to use blockchain, I moved most of my money over to electrum. Electrum is actually really simple to use especially if you can access the android/pc app. Use blockchain if you don't have much money to transfer, but even then I'd say use electrum over blockchain during any opportunity you get.
