> The CLR offers a lot of functionality that the JVM doesn't (see Someone123's comment)

Yes, some, but those differences are being quickly erased. The most important one is value types, which are being added to Java. See my reply to someone123.

RyuJIT's capabilities are nowhere near HotSpot's (I'd say they're about 7 years behind), and HotSpot's next-gen JIT (Graal) is another huge leap forward. The CLR's GC is also far behind HotSpot's selection, let alone offerings by other JVMs (there are many JVMs to choose from).
