From what I have seen this summer, it would look like this:
Tier 1: YJ Rose M&D Black Skywalkers Blue TLC Red
Tier 2: YJ Grazedei Elevate Blue Liberty Black TG Black Capital Blue Steps Blue SJ Select Pink NEMS Hero's Rebels Black MC Elite Coppermine Black and a few more I'm missing
Bottom line is that the four "Tier 1" teams a step above everyone else then there are about 20 very good teams in "Tier 2" that would be competitive with one another.
Is TG black really not a top tier team? Haven't seen them play in a long time and don't know who they have beaten or lost to lately, but last I knew they were close to top a couple years ago.
