What I get with the (much hated) Microsoft stack:
- C# with LINQ and async await
- Roslyn compiler as a service which speeds up development
- mature .NET framework
- more and more open source and cross platform parts and smaller independent libs
- typescript
- Xamarin cross platform tools
I also use python and used Java in the past. I don't see any reason why Java should be better?
- Groovy is nice and still very similar to Java(no learning curve)when you want syntactic sugar like LINQ or JDBC SQL without all the boilerplate code.
- IntelliJ Idea is similar to Visual Studio + Resharper.
But the biggest reason to start using Java is its extremely mature and rich ecosystem!
I'm currently doing software development on Windows with C#.Net and Visual Studio without ReSharper and I really miss Linux, Java and IntelliJ Idea :(
I am wondering how asp.net on linux will stack up! should be interesting.
