Well I may try ! I'm not very religious, I used Java for everything since I've started programming and I work in low latency in an investment bank now. I adore Java, it's my truly native programming language, I try to know all of its quirks, study each new version and know still not enough to satisfy my love of it. I also did a lot of C# to help on a GUI optimization project (because doing low latency if the GUI freezes every 10 minutes isn't great), and I was really surprised by how good it was so I wouldn't disagree it works nice. BUT I like that Java works simply in linux, I like that it didn't yet got contaminated by all the crazy constructs from elsewhere (Groovy grr), I love the tradition around the syntax (I can't stand C# quirks sometimes). I do HATE with passion the meaningless generics, and I wish we'd ditch backward compat to steal it all form C++ templates. I enjoy more than the language syntax itself that is close to most languages I like (Javascript, C#, C++), the team spirit around it. Believe me, it's much easier to use and understand maven (or maybe gradle who starts to get dangerous in real world projects where you can't afford 2 weeks of reverse engineering a madman's build script) than it was nugget, it's easier to use IntelliJ than to receive yet another stupid email from compliance about a Visual Studio license missing, it's nicer to build a jar and run it than to go through all the kinks of exe files... I dunno I may have started from Java and got to C# and done the opposite of your journey, but while I agree C# has superior features in some aspects (but sometimes they chose mess vs safety) I just wasn't convinced it could work for something more critical where you must do things as simple as you can, as clear as you can. And let's not even start on C++ who's superior in every conceivable way except that it encourage, or doesn't discourage, every team I ever meet to create unbearable messes they can't fix, so focused they are fixing problems we can't even imagine in Java for reasons we can't comprehend our company even accepts to finance :D
