As someone who spent years building "HTML5" JS mobile apps and then recently spending the time to learn native languages, I 100% agree. There is no way to match the performance and consistency of native with a cross-platform clone. It will always be a half-baked solution.

That being said this only applies to apps. A ton of apps shouldn't be apps, they should be well-optimized websites. For ex. content sites.

Side Note: Learning Objective-c and Android java dev isn't nearly as bad as I thought it would be. It takes less time to learn and build native instead of trying to hammer Javascript into a hole it doesnt fit into, and spending hours attempting to optimize it's performance to no end.
