I have been using Bitcoin Core because unfortunately I have some Bitcoin in my Armory wallet and would love to get Armory up and running so I can get my bitcoin out of there and not have to use Armory anymore.
You don't have to use Armory.
As suggested by LoyceV, you can use a SPV wallet like electrum to access your fund. In a SPV wallet, you don't have to download the blockchain.
In order to access the fund using electrum, you must export your private key(s) from Armory. To do so, follow the guide provided by HCP. (Click

In electrum, create a new wallet, select "Import bitcoin addresses or private keys" and then enter your private keys.
Warning:
Download electrum only from
its official website and do not forget to
verify your download.
