So It is clear that Itachi, Jiraiya, Shisui and Nagato are 4 people Obito would rather never have to deal or dealt with. This is a really good analysis. Itachi, Shisui, Nagato and Jiraiya are four shinobi who are among the strongest.

In no specific order, they are (but not limited to):

'''The Kages, obviously. Itachi, Naruto, Kakashi, Sasuke, Nagato, Madara, Obito, Jiraiya, Guy, Darui, Orochimaru, Shisui, the Akatsuki members, the Jinchuuriki.'''

I believe that fights among any of those would be much more about being able to counter-attack and read the enemy correctly than by using skill alone.
