As self appointed arbiter, they actually aren’t too different from one another. Looks like a little bit prettier PIP effects, the multiple window navigation, are main visual differences that look better but don’t actually changes the experience imo. The introduction of title screen transitions was nice, videos like these the best thing you can do is organize by topic to make it somewhat scannable.
