I use MetaMask and Myetherwallet as they're safe and easy to use. I believe as long as you have store your private key somewhere safe you should be good, so highly recommended. If you're willing to spend few $$ I'd recommend ledger nano s.
Be careful with your metamask because there are some reports that some holders had been hijacked and the memory was compromised. Seems no more safer this time other than hardware wallet and a safe computer that is virus free OS system.
Ledger Nano S is indeed beautiful hardware wallet that will offer you peace of mind and a full night time sleep.
Soon i'll be ordering my own Ledger Nano S for my crypto assets so that I wont think of getting hacked and hijacked on my android tablet and phone.
