Armory has lots of security features and things that other wallets don't have, but it runs on top of the core, so have it may be troublematic, up to you decide if Armory is the best or not
Armoury is hard for Newbies to work with because of its more complex nature. I would recommend Coinbase or Blockchain...Coinbase more than blockchain because those wallets are virtually immune to Bitcoin heists and hacker attacks.
