The Aeris/Aerith debate.

I personally do not care what her "correct" name is supposed to be. Regardless, I will probably continue to call her "Aeris" until the end of time. "Aerith", to me, sounds like "Aeris" is attempting to be said by someone with a lisp.

I've always considered it to be subjective - each individual can say it however they please. I say "Aeris" because it's prettier; it flows easier and is more pleasant to my individual set of ears.
