Assuming Vali's attacks can connect. Apparently, you are forgetting that if you were to compare the operational time of the Cardinal Crimson Promotion and Emperio Juggernant Overdrive combined with the sheer experience of the users, Issei would still have an edge, if a slight one. To say nothing of my belief that Issei is an embodiment of a theme proposed in the movie: "Captain America: The First Avenger." The theme being that a individual who was born weak would become strong while their respect for their growing strength never waning. A person who was born strong, by this logic, would eventually lose respect for their strength. In this case, Issei was (re) born weak and strived to become stronger, even more so when fighting Vali for the first time. In six months time, Issei matured and obtained enough strength to stand on par with some of the Underworld's finest. Vali, on the other hand, didn't do anything to nurture his strength. This, combined with the information from his wiki entry, leads me to believe that he believes in his power, but does not respect it. An example of this can be traced back to volume 9 when he recieved word that Issei was attempting to replace his Juggernant Drive and achieved initial success through Illegal Move Trident. It was after this that he began laying down the foundation for an improvement to his              Drive. The end result: Emperio Juggernaut Overdrive. Is it powerful? Yes. Is it similiar to Issei's new form? In some key ways yes. Can he use it to defeat Issei in CCQ mode? No. Why? For one, Issei can outlast Vali in their respective states. Why? The answer is simple: Issei was weak and devoted himself to becoming stronger. Truly stronger. Vali, on the other hand, was born strong and hasen't done truly done anything to make himself stronger. The most he's done is optimize his          Drive into its new form. When you get down to it, the only thing I can see that would seal Issei's victory in a fight is unbridled and unparalled motivation. Well, in my opinion at least.
