I'm glad this threat is at least starting to be taken seriously. As an amateur radio operator, I got incredibly interested in how the weather on the sun affects radio propagation and power management here on Earth.
Better a CME than an EMP just simply because there is at least some time to prepare for a massive CME. Whereas an EMP has absolutely no warning whatsoever.
In the event of a massive CME off-grid homes and buildings are likely to fare much better because they are not connected to the power grid. The problem comes with long transmission lines where incredibly large charge differentials can build up over distance. shorter wires can't build up nearly the same amount of charge differential.
Edit: I feel it's important to mention that grid tie systems are going to be just as vulnerable as on grid because you still have the grid actually physically connected to the building.
