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.
