Comparison To Diff
In general terms, diff is a more powerful utility than comm. The simpler comm is best suited for use in scripts.
The primary distinction between comm and diff is that comm discards information about the order of the lines prior to sorting.
A minor difference between comm and diff is that comm will not try to indicate that a line has "changed" between the two files; lines are either shown in the "from file #1", "from file #2", or "in both" columns. This can be useful if one wishes two lines to be considered different even if they only have subtle differences.
