While I was designing a board I thought, if we want to make a better path for the current what is the best choise?
Small vias and big in numbers or fewer but with bigger hole?
Electronic – Many small via vs few bigger via

This depends on what your end goal is but the answer is pretty much always use many smaller ones.
The first point has diminishing returns however, and you shouldn't try to make vias as small as possible. Too small and they no longer use a drill, but a laser, and your PCB cost just quintupled.
