#1: Gemini: The Duplicate Finder

Gemini is a very slick little app that makes finding duplicate files a snap. The slick, user-friendly interface is easy to use and understand. In addition, Gemini also supports scan your iTunes and iPhoto library for duplicates. It seems a good choice if you only want a slick interface. However, the interface might be just a little TOO simple for some people, as there are not a lot of options to allow things like setting up folders you'd like excluded from results. Gemini provides Auto-select feature for users, but its auto-select tool is a bit of a curse. If you don't pay great attention to it, you may accidentally delete an important file if you're not really paying attention. 

Pros: Great interface and easy to use, super fast speed.

Cons: Do not have filter option; the interface is too simple to some option lack; only delete the duplicate files of local folder, cannot delete the file at the dropbox; can't searching for something very specific and auto-select tool is a bit of a curse.

Also, you should be careful when choosing which duplicate files to remove as it is possible to delete files you actually do need pretty easily.

Pros: Scans quickly, powerful file scanning capabilities.

Cons: Interface feels a bit old-fashioned, its free trial has too many limits, it only allows users to get a sense of what the interface and navigation are like, users know nothing about what the program can actually do and how smoothly it will run; it is not a smooth process when scrolling through the list of scan results with the mousepad.
