The end result is more of a grab bag of minor updates and improvements than a full-fledged overhaul. Think of it almost like iOS 12S. Or to extend the analogy I made last year, if iOS 12 was a heaping plate of healthy vegetables, iOS 13 is a bright, colorful candy bar. But just like a meal of junk food, it leaves you a little unfulfilled in the end.
