The distance between nodes in 2 is ideally calculated as "distance along path", here's the formula: http://www.cit.gu.edu.au/~anthony/info/graphics/bezier.curves

Actually, for the purpose of comparing lengths, you don't need all that math. Just sum the length of both Bezier handles that define the segment, plus the distance between the ends of these handles (in other words, sum the three of the four sides of the quadrilateral into which the bezier curve is inscribed). This is a good first approximation of the curve length, at least it should be sufficient for comparing lengths of segments.
