I spent a minute looking at the output and realized there were a bunch 
of hits inside pydoc_data/topics.py, aka documentation.  And then I 
realized I was only interested in definitions, not docs or calls or 
other hackery.

Removing pydoc_data/topics.py and changing the search terms results in:

    "@property" 375 hits
    "def __getattr__" 28 hits
    "def __getattribute__(" 2 hits

Unless the average use of __getattr__ serve in excess of 13 members 
each, property is the most popular technique of the three.
