Dance Moms Miami vs Dance Moms

If you have watched Dance Moms, i'm sure you have watched Dance Moms Miami! Does anyone see a difference in the shows?  I see a few.... in Dance Moms the mothers get along much better than Dance Moms Miami! But the Dance Teachers at Stars Dance Studio from Dance Moms Miami are more loving towards his students unlike Abby from Dance Moms.  Does anyone agree?
