I perceive this as well on the boys side, fwiw (although my son isn't at that level, so my perception might be skewed).On the boys side it's different.
I have a younger younger playing as well and in tournaments you could clearly see how much influence MLSN has on which clubs boys/parents choose to play for.
That is, MLS Next (academy teams) is the top tier, followed by probably EA, then either NPL or ECNL, depending on the teams. But ECNL certainly isn't the top tier in my perception. There are some teams in ECNL which are lower ranked than some Socal flight 1 teams, for example. The top players from our club have gone to MLSN academy teams.
