> Even on the fastest phones, web-based (including wrapped web components) simply don't offer the native experience. They come close, but there's always a slight but perceptible performance difference

Honestly I used to believe this, but not after the release of the iPhone 5 and 6. Though there is no perceptible difference, it takes a lot of work to mimic the UI in terms of animations, opacity, and response actions, so most apps just use the default web technology which include things like a built-in 300ms delay, no response to clicking a link, etc.
