If UX encompasses UI, how is saying that he wants 'the best possible user experience' incorrect? UI performance and bugginess has an effect on user experience.
I'm just counter nitpicking at this point which isn't much better.

Sure, it doesn't necessitate a superior UX, but it certainly has an effect on UX. Here 'programminggeek' has tried building apps using native and using web technologies and has found that, for him at least, native provides a better UX. Are you saying thats not possible? That the choice between native and web is absolutely not a UX one but a UI one?
