I don’t use either, so I rely on the reports of others, and I’m thinking about posts that I referenced in a call-out for iOS beta testers where some iPad users described problems that iPhone users weren’t seeing. I know the OSs themselves have some differences, and supposedly Apple is making some changes to align the way they’re versioning OSs across their product lineup, but I don’t know if that equates to more future parity between iOS and iPadOS (and, by extension, would potentially result in a more uniform UI experience between iPhone and iPad Wyze app users). 
That probably makes more sense at this point.
