There are many document compare tools that claim to be the fastest, the most accurate, and the easiest to use. Actually, the speed of comparison is never an issue unless you are designing a high performance system. As for accuracy, any software will highlight all the differences for you, the questions are if it is easy to:
- Read the results of comparison
- Make some conclusions from these results
- Share these results if needed
That’s where the real difference between compare tools is.
