So this is no real difference between the JVM and .NET. Value types, yeah. I really do hope John Rose's ideas about tuples will get in to the next version of Java. They would do all we need for value types, really. (almost at least). Also, first class functions. This area I'm hazy on, but doesn't C# just synthesize them into class implementations, just like the Java proposals for closures will do? Delegates definitely doesn't have any real VM support.
So I would say that value types are the only real thing missing in the comparison. Of course, the JVM has lots of things that are missing from .NET, including a very advanced hotspot engine with both selective optimization and deoptimization. >> Also, stating the compellability of OCaml/F# over Lisp/Scheme is >> something I'm definitely against.

I've enough of both that I can't declare any of them superior to the other.
