I think the best bet in evaluating the iOS version is to consider the app on its own, not in comparison. The interfaces are different; similar functions are sometimes found in different places. Some differences are subtle: for example, both versions have a Quick action button, but the iOS version has fewer options. And. surprisingly, it has no POI overlay labels. Some recent Android feature improvements, such as in Settings and Favorites, are not (yet) on iOS. And conversely, the iOS version has a 3D view; the Android version doesn't.
My take: while the apps still aren't functionally equivalent , the developers have come a long way in narrowing the gap.
