It seems to me that MacDraw is maybe more user-friendly (to non-experts). It easily allows addition and deletion of points. Very convenient indeed. This leads to beautifully controlled weeding out of superfluous control points. I miss a tool for cutting and joining paths. Am I blind? (Yes. Do it at the polygon level.) The theory for MacDraw is neat. The b'ezier endpoints are the midpoints of the edges of the given piecewise linear path (polygon). The two b'ezier curves that abut at the midpoint of an edge are there tangent to the edge, and the two control vectors point to the two adjacent vertices. Except at the two endpoints that are regarded as midpoints of a prolonged edge. It seems most reasonable to realize the MacDraw path setup. The Adobe Illustr. and MacDraw setups are both well behaved under affine linear transformation. Knuth&Hobby are only invariant under rigid motions and scaling. LS> PS.
