Would just like to add to this answer that, as of Android 4.4, the WebView is based off of Chromium, enabling you to perform remote debugging with your chrome web developer tools (basically everything you can do on a website you can now do on a WebView).

I'd still pick native any day. Control > ease.

That's true, but sometimes things work just fine 4.4 and only break on the undebuggable Jelly Bean or older ;)
