Meter base suppressors (supplied by the utility) provide protection. The
IEEE surge guide talks about the length of wire used to connect a
service panel suppressor - as the wires get longer the let-through
voltage goes way up. In a meter base suppressor the earthing system is
usually connected to the service panel neutral. That means the neutral
wire from the meter to the service panel will raise the let-through
voltage of the suppressor.

The meter base suppressor works best if the ground electrode conductor
lands in the meter base.
You really want your grounding paths to be as short and straight as
possible. You also want your cable and phone suppressors grounded
right there.

The plug in, point of use protection is just supposed to be
supplemental to that. A good plug in protector will also have smaller
capacitors and maybe an inductive element, meant to shunt off high
frequency transients (noise).
I live in a place with a thunderstorm just about every day for 6-7
months of the year and I never unplug anything ... but I have several
layers of protection for everything.

We had a bad storm system come through The Southeast last week and I was
sitting at my computer when I heard my UPS click and my electric heater
reset/shut off (electronic control) then a few seconds later a very loud
BOOM almost knocked my out of my chair. Computers and network equipment
never skipped a beat but my heart did. :-)
