Specs
Question Ranking
Pros
Pro Supports comparing folders
Beyond Compare can be used to compare both files and folders. File-Filters possible.
Pro Supports 3 way merge
Good overview. Clear display of changed lines (background color) and changed characters (foreground color).
Pro Supports editing files directly
Pro Has rules for adding ignore-masks and replacement rules
So parts you don't want to see in your comparision can be hidden with ignore masks. Parts that are okay to be changed can be set with change-lists so beyond compare knows what's the replacement value and skips displaying this. So you can focus on the for you important changes. For example with the ignore mask I was able to compare two logs with different timestamps but nearly same content. (beginning with timestams the first x characters adding to ignore)
Pro Synchronize folders
Can be used to synchronize folders. Including wildcards.
Pro Works well with large files
Pro Can be used to compare image files
This is a useful feature for game developers using Git.
Pro Opens popular archive formats as directories
Compare archive to directory or to another archive, update ZIP archives by copying files from other side or by editing them directly in compare view.
Pro Can compare remote directories
Beyond Compare can compare directories through FTP, SFTP. Also it can compare directories hosted on Dropbox or Amazon S3.
Pro One license covers all major OSs (Linux/Windows/Mac)

Pro Has Registry compare
You can compare Registry vs Registry or Registry vs .REG file, both local and remote. You can copy values and keys between sides or edit them.
Pro Has file conversion/preprocessing feature
You can run a script or executable based on file extension before showing a file. Great for beautifying XML, extracting text from MS Office documents, running dis-asm etc.
Pro Supports 3 way merges
For modern version control systems, 3way merge support is a basic requirement, but many other open source diff viewers do not adequately handle 3way merges.
Pro Free and open source
KDiff3 is completely free to download and use. It's also open source released under the GPL.
Pro Can compare directories
It is able to compare whole directory trees.
Pro Supports editing files directly
In addition to comparing two files it also allows you to edit the merge result right in place.
Pro Diff by character not by lines
On comparing two files, difference is shown by characters; not by lines.
Pro The UI is customizable
Allow customizing colors regardless of user/system theme.
Pro Supports manual code aligning
With selecting code in one window and hitting Ctrl+Y, then selecting some other code in second window and also hitting Ctrl+Y you can manually align the code.
Pro Preprocessing before calculating differences
There are options that may pre-process compared files before Kdiff3 actually do a comparison - to ignore for example automatically generated dates and/or revision numbers added by commit hooks.
Pro Context menu shortcut
You can right-click a folder/file and the options:
- Save <file> for later
- Compare with
will be available, making launching KDiff3 really convenient.
Cons
Con No dark mode
Lack dark mode.
Con No touch support
This is important for scrolling
Con Paid proprietary software
Beyond Compare is not free. It offers different license options depending on the number of members in a team and depending on the software version.
Con Cannot do inline diffs
Comparison of 2 files is always side-by-side and there's no option for inline views. Overall a rather poor and confusing UI in general.
Con Confusing GUI
4 sub-windows (when you really only need 3), a lot of different colors and even more confusing result-window. No links what has changed between versions and and the result. It clearly shows it's dated or rather outdated. Great if you ever need to do a command line merge, otherwise it sucks.
Con No precise editing of the compared files
Precise work line-after-line is not possible. Only a version after the automated merge-step is editable, but not the two files separately.
Con No longer supported by Homebrew for MacOS
Cannot be installed easily on Mac as of Aug 2019.
Con Problems when files have different number of lines
For example, if you add 3 lines: A, B and C locally but on the other change there are only A and C, Kdiff3 will work out that A was added, then it says that B conflicts with C but adds C again anyway.
Con Slow for large files
Con No image compare
Compare is text based.
