Pros
Pro Allows you to open diffs in external diff tool
Instead of creating a new tab with the diff in it, you can tell FileDiffs to open the diff in an external diff tool for side by side comparison and other features.
Pro Easily compare arbitrary code sections
FileDiffs allows you to compare any arbitrary text through multiple commands:
- Compare the current file or selection with any other file via a file select menu
- Compare the current file or selection file with previously selected tab or window or panel
- Compare the current file or selection with your clipboard
- Compare between two selections through Sublime Text's multi-select feature
Pro Command pallet integration
In addition to providing shortcut commands for custom shortcuts, FileDiffs adds new command pallet entries. If you don't use diffs often enough to warrant memorizing a new shortcut command, the command pallet provides a quick and easy way to access the plugin.
Pro Three-way diff allows easy merging of files

Cons
Con Doesn't have side by side comparison
After running FileDiffs, it creates a new diff file in a new tab, which doesn't have the benefit of showing the diffs in context. However, it is possible to open the diff in an external diff tool instead of creating a new tab.
Con Bad tech support
Con It's NOT Open Source
You can't fix or, implement nothing. And when the developer abandons the project you will be left in the lurch.
Con It's not free
Nither as free price nor as free in freedom.
Con Cannot compare text within the same file
Sublimerge can only compare entire file diffs, but not two selections within a file. Comparing within files can be useful for example, by refactoring two similar functions to use a shared function. With Sublimerge, you need to copy the sections into two new temporary tabs and compare between the two. This can be cumbersome, as if you have another untitled file, you won't be able to know which one is which.
