As compared to search options of Registry Editor, there is additional Case-Sensitive Search option. Search time is several times shorter. You can also search in all copies displayed in the main window at once.
Search results are displayed in a special window as lines containing the path and, probably, the Value. By double clicking on the line you can open a tree in the respective Key; if the main Key shown in the line is not active at that moment, it is opened, which takes some extra time.
The only difference for search in compare window is that there is a new field "Tree" showing in which tree the object was found ("Deleted", "Added" or "Distinct in data")
