It depends a lot on the use case of your application. The size of the task, the amount of return use, etc. For one-off, low usage apps a web app can be the better choice.

Also, it depends on how good you want the app to look and behave. With HTML you don't have as much control over how content is loaded, animated, etc. Be prepared to deal with really hard to debug crashes if you're making a heavy app.

Last, but not least, the frameworks: the amount of effort that has been put into the native frameworks makes up for a lot of the (perceived?) ease of using HTML, but having to invent a lot of wheels. But again, it really really really depends on what your app will be doing.
