I will always prefer Blockchain wallet, it has a very simple design and a user intuitive interface, which let's even new users find their ways around it.
I have been using blockchain wallet for bitcoin for the last five years. It is very secured to me because i use all of the security actions including mobile sms, email verify, back up key, 12 backup pharase, password, google authenticator combinedly. So blockchain is the best secured to me and i will use blockchain for bitcoin wallet as long as i can.
