Native Apps vs HTML is just a microcosm of proprietary vs open standards which is always turtle vs hare. In short, native apps can always be better as long as they stay ahead, but the progress of open standards is inexorable because it provides greater portability benefits than any one vendor can match. Furthermore, it's possible to slow open standards as Microsoft did in the early 00s, but it requires immense market power and sacrifice of the user experience which is why Apple chooses to simply stay ahead of standards rather than letting mobile safari rot on the vine.

There will always be things native apps can do that standards can't, but open standards will always be more accessible and they will just get better and better.
