OK, a bottom-line question...

Other that whole house protection, IN YOUR OPINION, does an effective,
plug-in UPS exist?

Five general type of power problems exist: blackouts, brownouts,
surges, harmonics, and noise. Which one(s) need to be solved?
Different devices address different problems.

For blackouts and brownouts - short term backup - a battery backup
UPS will maintain power sufficient to protect data. Computer grade
UPSes should only be used on computers / electronics. Better grade
UPSes are necessary for appliances with small electric motors. This
because computers / electronics have such robust power supplies making
'dirty' power from a computer grade UPS sufficient.

Another type UPS is a building wide solution. These tend to be for
longer power interruptions, may be integrated with fossil fuel driven
generators, AND often have that short connection to earth. Building
wide units can include surge protection since a short and dedicated
earthing connection exists; since these type units are typically
located at the service entrance.

No preferred single solution exists if power problems are not first
defined. Above are some examples to demonstrates how different UPSes
address different types of power problems for different types of
appliances.

Noise and harmonics should be made irrelevant by the design of a
computer's power supply.
