I was talking with a customer last week about ColdFusion & ASP.NET and they contended that ColdFusion was just like ASP.NET and while in 1.1 that was somewhat true as far as the front end development goes but once you look you miss a lot if the things that make .NET development so nice in that you can separate code in to layers (UI, Biz & Dal) and now with ASP.NET 2.0 and the provider model flexibility, Master Pages, Web Parts and so much more I don't think the argument can be made now.

For some back ground on ColdFusion & ASP.NET check out the MSDN article Migrating from ColdFusion to ASP.NET is has an interesting comparison of features.
