PS. Who am I?
Just an electronics designer with some designs long ago in 2-way pager systems that were deployed in far off places that had to endure near lightning strikes. No one I know will warrant a direct hit (AKA "hand of God.")
My personal choice has been to protect everything with many devices. Anyone that thinks a single box or two will soak up the hit is dreaming. Add protection as you can over the years and in a short while your whole house total protection will add up to a lot of Joules.
