For Power Poles, Tensile strength is more important

The poles have to be able to bend in strong winds and under the heavy loads produced by blizzards and ice storms. Poles in the middle of fields have a lot less chance of being impacted by anything.

Impact strength is more important for poles close to roads. If the poles are used as light standards then I can see that being a major issue.
This is one of the reasons that Resin Systems decided to make it's poles sectional. When impacted by motor vehicles they would break off at the section's tip which lessens the damage to the vehicle as well as the severity of injury to the occupants.
