Again why does it matter, only the expensive electronics need it. How much does the whole house protector even cost? I think the expensive surge protectors are better for fine equipment , then again its debatable if it matters or not.
Not really if you think about it the PC and game system/ TV are the only electronics that it might be worth it for. If your computer is worth 1000 $ it might be worth it. Same with the playstation/entertainment system.

Maybe but there is a little more to it then that. Then again maybe a better surge protector isn't worth the price.
Yeah the really cheap ones maybe. The protection system is rated in joules or something. Also there are additional measures of protection in electronic jargon I can't explain. Surge protectors protect against very small but constant "surges" in the line. Its not like what people think- they protect against lightning strikes or massive surges. Its the small surges over time that cause problems. Or maybe we are being sold another gimmick I don't know.
