I haven't heard back from the jcat people yet, but one thing that seems great about it is that there's only 1 scale. So during your entire time studying Japanese you can easily see improvement and compare your level. With the JLPT it's pass/fail and the levels change. So between passing the N4 in December 2014 and failing the N3 in December 2015, I get no outside verification or quantification of my improvement.
In retrospect, I wish I took the jcat around when I picked up Japanese again in early 2014.
