Claiming your opinion is fact IS implying your opinion is better. That was my point, and my objection. Saying "this is fact" when it is your opinion. I'm comfortable to agree to disagree on the point of Gladion being better or worse than Lillie as a character, though.
Unfortunately, I highly doubt fan feedback will contribute to how much either of them appear; generally Lillie was very well received by the fans, and it seems likely they will want to pursue that in some form. Although the possibility that Gladion could replace Lillie as the hand-holding guide character, if these are alternate story games, is not entirely remote. Seeing things from his perspective, with a role reversal of sorts going on, could be interesting.
