Cursive is a vestige left over from when writing with quill pens or fountain pens was the norm. Beyond that, it's no different than printing.
One major difference. Words, and ideas, flow from the mind to the hand in a much smoother manner. Cursive writing was invented to prevent the, for lack of a better term, Stop & Go style of writing that is the nature of printing. With script or cursive writing, the tip of the pen gets lifted off the paper far less. Ideas flow faster from mind to paper. Swap out the fountain pen with a nice rollerball or an exceptional ballpoint, and the difference vs. print is the difference between a drag race involving a Ford Model T and a 2010 Cobra Mustang.
