title: does pyodbc have any design advantages over pypyodbc?
body: <p>I know <a href="http://code.google.com/p/pyodbc/" rel="noreferrer">pyodbc</a> is an older project and probably more featureful and robust, but is there anything about its design (based on components of compiled C code), that would make it preferable to a pure Python implementation, such as <a href="http://code.google.com/p/pypyodbc/" rel="noreferrer">pypyodbc</a>?  </p>
  
  <p>I do a lot of ETL work and am thinking of switching from a Linux/Jython/JDBC approach to Windows/Cygwin/Python/ODBC approach.</p>
