As I see everyone is talking only about electrum and jaxx.
I would not recommend anyone to use Jaxx. I just don't feel any confidence on using their wallet based on the amount of bugs and security issues still not fixed. I remember some time ago when a few users tried to restore the wallet with the backup seed and their coins went missing, just like it was another wallet.
And for sure the easiest and the best way is to use QT wallet. Don't to have it fully sync. Just install the wallet, take the address and simply save the private key. This way anytime when you will want to get to your bitcoins just go to blockchain.info or any other platforms even electrum wallet.
So... a paper wallet? If you don't plan to spend soon, there is no reason to download a wallet. Just generate the private keys and print it.
