Unfortunately, I don't think I've ever used a web app that feels anywhere as good as a native app. You can feel it in every interaction.

You say "a bit of scrolling hesitation". I say that... and janky button taps... and broken back/forward navigation... and browser chrome always getting in the way... and random divs constantly getting selected along with text... and mistakenly-tapped links taking me who-knows-where... etc. Plus: if the developer decides to shut down their web app, it's actually done, forever, with no recourse.
