the miles you mention are one thing, but performance was always more important to me.

java pendant c# was always much more performance focused than java, having structs, unmanaged c# and c++ interoperability. it took java 16 years or so to accept that structs have their justification.

i also find the c# language much nicer than java. f# versus clojure are both excellent additions and again, f# is the more static and performant while clojure has very nice and inspiring features and aspects. it depends on what one wants here.

finally i think even if java is the larger universe, the .net universe certainly is not small either. if .net would not have taken the cross platform road i would have switched to the java runtime, but happily the opposite happened.

I wouldn’t call it performance, but control. The Java and .NET world focus on different things - the JVM has a very very advanced JIT compiler and due to the programmer not being able to specify all that much about certain aspects of code it has a better chance of optimizing it (similarly to how SQL queries can be made very fast precisely because they are at a high level of abstraction). The CLR provides more control at the expense of less optimization opportunity. This escape hatch is really useful for some programs, but not all of them would benefit from it.
