I mean if there ever were films to watch a dub for its those. Disney does an exceptional job releasing them in the US and recording the dubs. I usually try to watch new ones of his and/or Ghibli films in the original format first and then I'll be fine with the dubs in the future for the reasons you state.
But if you seek out other anime in the future... know that most english dubs are notoriously awful outside of that whole circle. Laughably so.
