What I'm asking here is which Asari provides the greater access to content, the best war assets, possible romance options, etc.
I know that Morinth will be turned into a Banshee if you choose to kill Samara during her loyalty mission, but as I have never killed Samara I'm unsure on the rest of the details. Does this mean that she won't appear at all during Mass Effect 3 until the end, at which point she is already a Banshee? Does this prevent her from appearing in any of the additional DLC for Mass Effect 3?
I am presuming that due to Morinth being Ardat-Yakshi that any attempts to pursue a relationship with her will result in orgasmic death.
Are there any other content or gameplay bonuses to choosing one over the other?
