Not to play devil's advocate here but Collbrande-Ex-Caliburn has some valid points, mind you Issei is one of my top favorite anime characters. The hole in your arguement Collbrande is that your forgettting Issei has been in his current situation for only ONE year. All of the other characters you mentioned have had YEARS to hone their skills and abilities and also were probabily proteges. Issei is literally an average joe (Boosted Gear aside) who was thrown into an extraordinary situation that became his life and along the way he accomplished incredible feats despite his lack of gifts. So even if he isn't considered the strongest red dragon emperor yet he will become that, even Cao Cao acknowledges that.
