What is advantages of hardware HD wallet vs mSigna by Ciphrex

I tried using BitcoinArmory but its does not seem to be up to date.
And I need help in setting this up.

Also Can I set up a hardware wallet like Trezor or Nano S and set it up with multi signatues.

Can Bitcoins be accessed by using the Trezor/Nano and (GreenAddress) or does it have to be accessd through the node.

Where can I get instructions on setting this up?

Thank you
