For a specific object, you can open the Object Info and then the Observing Lists tab. This will show you every list that you have installed, in which this object appears.
SkyTools is designed more for planning rather than this sort of general list spread sheet stuff, but if you are creative there are ways to do possibly get at you want.
Sorting the lists in designation order might allow you to print (or copy to the clipboard) both lists and then you could compare them easily. This may be the best solution.
You might also be able to leverage the fact that a list can not have the same object in it twice. You could do something like this:
1. Create a new, empty, list
2. Open your first list and reset all the filter so every object is displayed.
3. Right-click on the red check mark column header and select "Check all"
4. Right click on any red check mark and select "Copy all checked to..." and copy all of the objects to your new list. This will make a copy of the first list.
5. Open your new list and check every object as you did before. This will mark every object that is in the first list with a check.
6. Open your second list and follow the same procedure to check every object in it, and then copy the objects to your new list.
When you open your new list any objects that are not checked appear only in the second list. You could right-click in the red check mark column and delete every object that has a check mark. The result would be a list of objects that appear only in the second list. One could imagine doing the same, but reversing the lists such that you would end up with a list of objects that only appear in the first list. I don't know how useful this would be, but it serves as an example of how one might manipulate the lists using the copy function.
