I'd suggest myetherwallet anytime of the day.
Going by the brand alone, you'll know they have their integrity to protect.

I don't even consider most of the prevalent wallets that you can easily get out there.
What if you fall victim to a scam? you''ll have all your coins gone.

Provided you can safe keep your private key, myetherwallet remains a sure bet. Other people who already have success in an alternative wallets can share their experiences.
