Auslogics Disk Defrag v. Defraggler....It's not even close

For those who have a passion for defragging their hard drive (Remember, no need to defrag an SSD Drive), I used to recommend two Defragmenters for the job.  Defraggler and Auslogics Disc Defrag.  Well, it's not a competition anymore.  Auslogics Disc Defrag is the one you should use.  Both do the job, but some unforgivable reason, Defraggler can take HOURS to complete, while Auslogics can finish the job in literally minutes.  I have no idea why the disparity in execution time exists, but it does and is almost unforgivable, at least to me.  This article came to mind as I sit her defragging a drive.
