Pros
Pro Offers good options for quickly dealing with duplicates
Once duplicates are found you can choose to select certain files based on criteria like when was it created, when was it last modified, size, folders they're in or if the folders they're in contain a particular string.
Pro Reasonable rules for finding both duplicate files and folders
The program can find duplicate files based on any combination of size, name, CRC. It can also compare files byte by byte. Also, it can compare folders (with or without subfolders) based on any combination of size, name, CRC as well as file count.

Pro Gives a clear overview of found duplicates
It shows duplicate items grouped with every second group highlighted.
Pro Works on all operating systems
Windows, Mac, and Linux are supported.

Cons
Con No (text) file viewer
Con No explicit bookmark support for directories
It though remembers the visited directories and allows to search in this list in most-recently used order and by name.
Con Mainly for key-board-orientated users
The interface is most naturally navigated by arrows and keystrokes. The target market is software developers.
Con Has no menu bar
Hence it is not well suited for visually orientated users which find or remember commands by using a mouse and a menu. Even the fman's hero Sublime Text uses a menu bar.
Con Requires email address to download
Doesn't say what it will do with this data. It is in contrast to the new laws in Europe where only necessary information is allowed to be collected. A download should not require an email address.
Con Still quite buggy
So, for example, sorting only is remembered if triggered by command and not be clicking the table column header using the mouse.
Con Settings can't be found by the GUI
You need to know which files to edit.
Con Default dark theme
No choice between dull-dark or fresh-light.
Con No portable bundle available
On Windows only a net-installer is available.
