This might not be very helpful, but for what it's worth, here are the two corresponding video reviews on Onahodouga:http://onahodouga.com/archives/54322388.htmlhttp://onahodouga.com/archives/54842128.html
The original is rated 4 stars, 3/5 stimulation, while the Hard is rated 3 stars, 4/5 stimulation. So as expected, it's harder/more stimulating, but maybe too hard. Appearance-wise, they look almost identical; the hard version is maybe very slightly darker in color.
