Google takes the exact same sales cut Apple does. And the Apple license is $99 versus Google’s $25. As to dictating UI, Apple has human interface guidelines and yes they actively curate their Store (something which Google has gotten blasted for not doing in the past when they have had problematic apps in the store). I could make a point that having UI requirements is a good thing for users if it promotes consistency in the UI across apps.
Really the only financial difference is Apple charges $74 more for their license.
