Liquor is quicker.
I've read if you scan an amiibo and your 3DS detects you own said villager and HHD, their house you designed will transfer over. Is this true? What exactly transfers over? Is the exterior design included (not the garden, but the roof choice for example)? What happens to homes with multiple rooms? I'm assuming only the immediate room is copied, but what if it's larger than New Leaf rooms? Basically, how does the whole thing work? I'm finding no concrete answers on this since the update.
