My son played on a team that played a mix of both last summer. Huge yes - it’s a massive jump when playing a true AA team (eg legit top 15 or 20) compared to A, which I see as most often in the 30 to 100 ranking neighborhood. And then a similar gap between a and b as you move outside the top 100. Ratings aren’t perfect but give you a good directional sense of who is AA, A, B from a tournament bracket POV.
