Well....
Whole house surge protectors usually have a rather high activation voltage. 350V or so and they take time to work. On the other hand they since they are close to the ground / neutral junction they have a good chance of working well vs. using MOV strips far from the panel. I think every home owner should invest in them, they are relatively inexpensive and placed in the right spot, but best? Not to my mind.
Zero Surge / Brickwall clamps under 200V and has no activation time.
The best solutions IMHO are a combination whole house + series mode protection, followed by whole house + Furman.
