All the hard work is always chasing down edge cases, scaling, operational issues and other things that don't show up the user-exposed features. And talking about features, the innovation in coming up with them, or iterating on making them work with real customer experience is a ton of value, even if copying the ideas that work later is much easier - which is why I generally prefer betting on an innovator with just of enough traction to show they can stick with it. The best category leaders both innovate and steal/copy/buy all the innovation they aren't producing in house to maintain their lead.
