It's most useful when you're using some data you already have as the dictionary key. A usecase i had for this was a binary file parser with 10 types of event markers. It was originally coded with if/elif, but performance was a pretty big consideration. Using the event markers as keys to a dictionary dispatch improved performance by about 15% and made the code significantly more readable.
