Idk, I feel like zig zagging would be more troublesome, doing it spiral fashion all you're doing is curving a bit, and even going straight in some stretches
I guess it would also depend on overall the terrain elevation of course, where it drops more and whatnot.
Also to be completely honest, I have 0 experience with this, it was just the first thought I had about building a road up a mountain.
Is it though? Seems zig zagging up one side “switchback” method is most common, and probably a lot less costly.

There is no road in the bottom right corner forming the triangle, Without this there is no pattern, just a standard mountain road with switchbacks
Nice catch.
