$\begingroup$ I'd be interested in how you're going to bore a square pile... Bored piles are always going to be circular, driven piles can be any shape. $\endgroup$– AndyTCommented Jan 21, 2020 at 15:58

It is the right foundation type that is the best. Not necessarily pylons or any one size fits all solution.
Design of foundation is a process tightly tied to the type of soil, geology of the site, building usage and many more factors.
When all these factors are worked together and the loads on the foundation are determined, there is a determination as to the type of foundation.
This can be a combination of footings and grade beams, mat foundation, or if the competent soil strata is deep, pylons.
In some structures a combination of all these is used because either the geology is not uniform or the structure massing and height varies.
