If you mean for getting a BCH wallet... then your choices are pretty much:

Full Node: Bitcoin ABC - Just be SUPER careful when installing and running it to make sure it doesn't overwrite all your Bitcoin Core install and data directory.
SPV: ElectronCash

I believe that it really comes down to want you want to access the BCH wallet for... HODLing or dumping?

If you just want to get BCH to dump it, I'd recommend that you get ElectronCash, export your private keys from Armory, import them into ElectronCash and then you can send them to whatever exchange you want very easily. If you want to hold, then, in the long term, it might be worth the effort to get BitcoinABC up and running and then sweep the private keys into your BitcoinABC wallet. ElectronCash could also be used longterm, but in that instance, you'd probably want to create a "seeded" wallet and then sweep your Armory private keys rather than importing them.

(NOTE: regardless of whether you want to import or sweep the keys, you should makes sure that you've moved all your BTC into a new Armory wallet prior to exporting the keys)
