Top dog of duplicate finders

I have tried many dup finders over the years and actually have 5 in my applications now but after going back and forth many times between these apps
I always default to Photo Sweeper as it has for me the best set up for finding and then checking over the found duplicates to insure I am not tossing the wrong one.
You do have to learn to operate with the interface a little but it seemed the most intuitive to me and I quickly learned to adjust it to my needs so I could rid my self
of many libraries worth of dups (iPhoto, Photos, Aperture, Lightroom ) saving me at least 100GB of HD space.
