I am late to the game but watched and recorded the semis and Finals and those were my impressions. A very proactive attack and scored in an abundance of ways. The one/two quick combos to a third runner at the top of the box were something I really haven't seen from an American Youth Team--and my best comparison was the 2019 U20 World Cup group that stunned France in the Round of 16. That group led by Chris Richards, Weah, Dest and Paxton Pomykal produced goals almost exclusively on the counterattack.
I was struck most by the wide variety of playing styles, especially from the Philly Union kids. A center back taking all of the set pieces in Brandon Craig, an 8 in Jack McGlynn who looks like Magic Johnson compared to everybody else as a lethal and creative passer--and with shots from distance. Paxton Aaronson as a 10 was attack, attack, attack with an attacking skill set better than his older brother without maybe his brother's sheer energy and range. Throughout the tourney this edition was miserable to play against with their counter pressing.
