NeoOffice is more "Mac-like", with easier installation, better integration into the OS X interface (pull-down menus at the top of the screen and familiar keyboard shortcuts, for example), use of Mac OS X's fonts and printing services without additional configuration, and integration with the Mac OS X clipboard and drag-and-drop functions.

However, it requires more memory than the X11 version to perform well, some functions are allegedly slower, and the additional code it adds to the main OpenOffice.org code base is not as fully tested.
