Venitas (X-Blade) > Master Xehanort > Terranort > Terra (full power with darkness) > Master Eraqus > Terra = Aqua > Vanitas > Ventus
Aqua and Terra had equal power when they fought each other at the start of the game, but this is with Terra not using darkness. Terra defeated Master Eraqus using his darkness, but would not have been able to defeat Master Eraqus if he didn't use it. Ventus is the weakest imo. I lost count how many times he got his ass whooped by Vanitas.
