I use myether wallet to store ether and erc20 tokens because it is very efficient and is not a hassle to use. It also does not require one to download one specific file just to use their service but instead one only needs his/her private key to import and use one's own ether wallet. If you need an easy to use ether wallet to store ether and tokens, I think myether wallet is the best to use in terms of it's efficiency.
