My first playthrough was as a Good Durge and yes that was a powerful moment, but I don't think I would enjoy as much the second time. Still haven't tried an evil Durge as I've read you lose a lot of content.
One thing I did find odd about Act III was how little interaction I had with Gortash ... maybe I did something wrong but I only interacted with him twice and both were pretty short.
the true powerful one should be tav, because durge is failed the trial in 15 years ago.
the fallen one suddenly becomes good, just because you put your soul into durge's body.
so the good durge actually is tav-urge, that in your control.
or you will only see the npc dark urge's pure chaotic evil.
