I used Armory for years, liked it but tired of using two computers for cold storage and changed to Trezor and have not looked back. Armory has been promising Trezor support but it never comes. I doubt it is a priority now. I am aware of the privacy advantages of running your own full node and Trezor owners will have that option soon according to this post on reddit. Mytrezor release with Bitpay Bitcore support is coming soon. If you do not want to run a Bitcore node on your own Linux box you will have the option in myTrezor.com to connect to other public Bitcore servers. Woohoo!
