At first glance, it seems to support geometrical operations that neither of those have built in. Things like "draw the incircle of this triangle" and "draw a perpendicular from a line to this point" and "find the intersection of these circles." So if you can construct your figure using compass-and-straightedge, you can probably cobble it together using the existing API without touching trigonometry or vector manipulations at all.
p5 and pixi seem to be more on the "just tell me where to put it, and I'll draw it for you" line. Pts has a whole bunch of higher-level abstractions where you can define mathematical and geometric operations to apply to your points:
