Protection involves two concepts.You think there's a worthwhile difference between the whole-house units from say, Intermatic or Leviton, and a high end unit from someone like Eaton Innovative Technology TVSS?
1) How well does it connect energy harmlessly to earth? That is answered by how the connection from utility wire to earth is made. Conductivity and equipotential provided by single point earth ground is relevant during one surge. That defines protection from each one surge.
2) How well does it perform over your lifetime? That is defined by another numbers such as its current rating. A protector rated for higher currents not only does paragraph 1) better. It also lasts longer. A 50,000 amp protector from Intermatic, Leviton, or Cutler-Hammer (Eaton) may be sufficient for most. To exponentially increase that life expectancy (and make the protector more conductive), a homeowner in Central FL, on the NM AZ region, or in WV may need a 100,000 amp protector.
The circuit inside a power strip protector selling in the grocery store for $7 is also found in a Monster Cable protector selling for $150. Price has little relationship to quality.
Same may exist (to a lesser extent) with 'whole house' protectors. A 50,000 amp Cutler-Hammer circuit selling in Lowes for less than $50 can also be sold (from a different manufacturer) for $150 from some other retail source. More important are manufacturer spec numbers - and understanding what those numbers represent.
This much you do know. A protector damaged by a surge was undersized for that surge. Undersizing his how ineffective plug-in protectors are promoted to ill informed consumers because eyes glaze over when numbers arrive. Paragraphs 1) and 2) define two most important considerations.
