get a whole house surge protector installed in/next to your breaker box to prevent nasty stuff from coming in over the utility line. then use decent surge protector strips as needed to prevent inside high load stuff (fridge/HVAC/pumps etc) from messing with power.
Nasty stuff from high load stuff is maybe as much as tens of volts. All appliances are so robust as to make that only noise. In fact, electronics convert those spikes into rock solid, low voltage DC to power it semiconductors. So called interior surges are myths. Numbers redefine that as noise.
Meanwhile that power strip protector is typically so grossly undersized as to also need protection only provide by a properly earthed 'whole house' protector. No protector does protection. The power strip is protected when a 'whole house' protector connects low impedance (ie 'less than 10 feet') to what does that protection: single point earth ground.
Protection is always about where hundreds of thousands of joules harmlessly dissipate. No power strip claims such numbers. Hundreds of thousands of joules cause no damage when absorbed by single point earth ground. Then computers, refrigerator, furnace, smoke detectors, clocks, recharging mobile phones, and power strip protectors are protected.
