Note that the Duo you say must exist, the two should at least have one battle as a Duo. Remember that all of them are at their best conditions. (For example both Madara and Obito are six paths) To me it's : 1- Obito and Madara 2-Hogoromo and Hamura 3-Madara and Hashirama 4-Naruto and Sasuke 5-Obito and Kakashi 6-Naruto and Minato 7-Sasuke and Itachi 8-Naruto and Jiraiya 9- Sasuke and Orochimaru 10-Kakashi and Minato

Note that Indra and Asura are not in the list because we don't know much of them .
