Really I think just the opposite. The English version gives me the authentic voices since most people in these iconic movies return to reprise their role. And I loved Aqua's english voice TBH.
I completely agree when it comes to all of the Disney voices and some of the original characters (not all though), and since the Disney cast makes up more than half the character, I much prefer to hear their original voices. Don't get me wrong, the Japanese voices are overall slightly better for nearly all of the original cast and by far for every FF character, but the Japanese Disney voices cannot compete with the original English voices imo.
