Good overview. Clear display of changed lines (background color) and changed characters (foreground color).
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)
