Not first hand experience as Zero *still* hasn't shipped the moto they promised last month, but I've looked into it a bit and can add to some info: Because there is no hot silencer to deal with, zero riders have soft luggage options without a rack that ICE motos don't have. Soft panniers are not as secure as locked hard cases, but can be locked and locked to the moto. The main pluses are lighter, cheaper and safer for the rider than hard cases.
