What are we using for tracking down duplicate files now?

As I go through another clean-up and merging of old drives in preparation for a new machine, I’m wondering what apps we’re using for tracking down duplicates. Is Gemini still the best, or is there something else people prefer now?

Gemini 2 from MacPaw? I just ran it on a large external drive this afternoon. It still works well for me.

I’m pretty sure Hyperspace only finds exact duplicates. Gemini throws the net a bit wider trying to find equivalences, such as two images of the same dimensions and ostensibly the same content with different file sizes. While this can find more ‘junk’, it can also show false positives — for example burst photography can be picked up as duplication.
