What's the best way to tackle these piers, should I be using a Structural Column or Structural Wall?
I prefere Structural Columns because, being Editable Familes , they coud receive parameters and so, they can be easy controled and scheduled and can also be used repeated in many instances.
Structural Walls I would using only for long elements with no much repetability..

In addition to what CS mentioned the choice might depend on the structural code to be applied. The Eurocode states that the width b of a structural column shouldn't exceed 4 x thickness. Otherwise consider it as a structural wall.
You must have the same material for the wall and column in order not to see the separation line between them...
It is normal to have a line between two diferent finishes or materials....
