RoR is definitely more of a full web stack than ASP.NET MVC, which to me feels like a micro framework layered over top of whatever in the the world ASP.NET is. Personally, I like ASP.NET MVC's micro fx feel though.
You hinted at Ruby not needing DI - for me, that's the biggest advantage when choosing a dynamic language (in my case Python) over C#. IMO, there's something about using DI that just feels wrong (don't mean to start a flame war over that).
Anyway, that's why I use F# in .NET land: the type inference provides the best of all worlds. No need for DI, light syntax, and great runtime speed. F# sucks w/ ASP.NET MVC though.
