It's dependent on the app's purpose. If it's social and you need to be on both platforms, I strongly encourage hybrid. A webapp is cheaper and can perform the same as an app with a dedicated backend. If you are more of a service app, an iOS version may be a slightly higher price than the webapp, but you'll have the experience of going through the Apple testflight testing and then their approval process. Once you get on apple, Google is easy. You'll also get a better idea of your target user's willingness-to-download.
I've worked with both native and hybrid. I'd be happy to find a time to discuss further if you like.
