As an example, I drove past two nearby poles today that carry two
lines, one 69 kV (the step between intercity lines and lines on every
street) and one below at a lower voltage. One was solid reinforced
concrete; the other was (presumably) hollow metal. Otherwise they
looked very similar; all the connections were in the same place. The
only visible reason metal rather than concrete was chosen for one is
that the 69 kV line turns away from the road there.

You can see the metal one here:

and the concrete one here:

There's no way I can see tagging one as tower and the other as pole
making sense.
