How do you evaluate code maintainability of HTML5 vs. Silverlight

Question

Comparison of HTML5 and Silverlight as Web development platform is a popular topic, and arguments often focus on readiness of HTML5 or additional step to install Silverlight plug-in. But let's say there are no such issues: all browsers have good support for HTML5, and all browsers come with built-in Silverlight. I know it's false assumption, but it helps me focusing on something else: with such assumption made, what would you choose for rich Web client development in a .NET development team?

I believe one of the important factors then will be code writing experience: how easy is to write clean code, how easy to maintain it over long period of time? Do you have any experience with this?

Answer 1

With Silverlight 4 and Ria Services I think it's getting pretty obvious that the future of the technology lies in data focused business applications (well.. and the coming windows mobile 7 - which would better use the Desktop WPF ...).

HTML5 will, IMHO be multimedia focused.

... WTFs per second.
