It's faster than both.

third_base was written by me in pure ruby.  It's not as compatible or as 
fast as home_run, and only provides the 1.8 API.  It usually gives a 
2-10x speedup over the 1.8 standard library version.

home_run is faster than Date::Performance, even in the cases where 
Date::Performance is used, and Date::Performance only handles a subset 
of Date's functionality (and none of DateTime's).  In general, 
Date::Performance is faster than third_base for the cases it handles, 
and slower for the cases it does not.

There are a few reasons why home_run is faster, but it's mostly due to 
the use of a different data structure and faster algorithms.
