I'm not sure, to be honest. They all kind of blend in for me, but as of right now I think it might be like this:
1 - Empire Strikes Back
2 - A New Hope
3 - The Force Awakens
4 - Return of the Jedi
5 - Revenge of the Sith
6 - The Phantom Menace
7 - Attack of the Clones
At least Phantom Menace had Qui Gonn, the badass fight at the end, Duel of the Fates, and i still love that podracing sequence. Attack of the clones really doesn't have anything of particular note. Revenge of the Sith has many, many awesome fights, and...really thats it but they are good enough to make me enjoy the movie despite plot issues.
