If you want a more peaceful and quiet view/experience, stick with island view. One of my favorite things about Aulani though is hearing the evening entertainment while we hang out in our villa with the sliders to the lanai open. I would have serious FOMO with island view as we also love being able to hear the happy noises from the pools, slides, and lazy river and see how long the lines are before heading down. For those reasons we only book ocean or garden pool for our trips. Many people are happy with island view though as they are able to watch the luau from their lanai - definitely a personal preference thing.
