I've used ASP.NET MVC since 1.0 ( ~2 years ago ) for a few projects. It's a pretty nice framework. It's still evolving, so it's not quite RoR/Django yet, but it's really close. I wouldn't go near WebForms anymore, though you can integrate the two.

Aside from ASP.NET MVC, there's a few other frameworks out there. You can check out the web parts of Spring.Net ( http://www.springframework.net/docs/1.3.0/reference/html/spr... ) or MonoRail from Castle ( http://www.castleproject.org/castle/projects.html )
