>>24676891Nah, GF got it right in BW/BW/XY, it makes no sense for one E4 member to be stronger than another, they're each meant to be god tier, only being surpassed by the Champion.
Pokemon battling is like sports, the higher up the ladder you go, the less of a gap, skill, technique and mentally wise, there is between teams and players. Top tier teams are usually just about as good as one another, the only difference is that on a particular day, one of them will perform better and beat the other, and then the next time they play the team which lost will perform better and win. The same is true for Elite 4, all of them are capable of losing to and beating the other, it just comes down to who performs better on that particular day.
In terms of the Champion, just think of them as being like Guardiola's Barca, a freak even better then the best teams. They're capable of being beaten the Elite 4, just like Guardiola's Barca were beaten by the likes of Chelsea and Madrid, but if both the Champion and Elite 4 member are both performing at their best, the Champion will still win because they're best is better than the Elite 4's best.
