ASP.NET AJAX vs jQuery in ASP.NET MVC

Question

Which one is better to use in ASP.NET MVC?

Answer 1

Instead of making a recommendation I suggest you read Dave Ward's blog Encosia that has a series of posts on MS Ajax/ Update Panel vs. jQuery post mechanism. Dave maintains that the performance of jQuery is vastly superior as it cuts out approximately 100K from the transmission to and from the server.
