There is really no advantage over outlets in the wall to the plug strip device, unless you have transient protection on them. The cheaper ones are MOV's and are "one shot" or their clamping range is nearly worthless, so be very careful, cheap can damage your equipment.
IG outlets are also nearly worthless since most problems, even in commercial locations, occur over your neutral conductor, not your ground. I would not consider them for a house.
Sparky, just copy and paste this one, it's easier
