Lightning is about a connection from that cloud to distant earthborne charges. What is a best connection? What is the geology beneath that house? Often lightning may strike a valley; ignoring adjacent mountains. Because that valley contains relevant geology. More often mountainsides rather than mountaintops are struck. Lightning rods are important for buildings more often struck due to geology and other external factors.
Does not matter if adjacent buildings have lightning rods. Its cone of protection is typically 60 degrees beneath that rod. Adjacent buildings (without earthed lightning rods) remain just as exposed.
Lightning rods do not attract lightning. That strike is going to happen no matter what. Homes with lightning rods mean no damage IF rods are properly installed (earthed).
