I would think web apps have the major advantages, and have for some time.

Seems to me the biggest draw one would be see how you can retain the people that are willing to go the extra mile to download your app. You must be solving a problem for them in a significant way. A web app is a quickie, it's useful or isn't. And besides the reasons why they are useful above, it helps you to fail /or/ scale faster.
