Excluding Lib/test, there are 375 uses of "@property" in the stdlib in trunk, 60 uses of getattr, and 34 of getattribute.

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.
