I haven't personally used it so I don't have much to say. It looks like it requires a commercial license so that doesn't get me particularly excited about it.

I'm also not sure how hard Qt actually tries to give you UI components that look like what you would find in a typical app. If you have Qt experience then I'm sure you can make it work, I've heard good things from people who have used it.

I'm also guessing it has much more consistent and robust UI behavior compared to running things in a web view.

You'll have to find someone who has actually used it though to get a real opinion, I'm just speculating here.
