Won't argue about Eclipse performance. Sometime it depends on the characteristic of the project. Some of the projects that I worked on, albeit huge, Eclipse still performs pretty nice. While in other instances I do notice issues with the performance. Tomcat and Jetty make a lot of sense if you use it with Maven. The ability to compile, deploy and bring up your App Server is something that you don't get for free in .NET http://mojo.codehaus.org/tomcat-maven-plugin/deployment.html http://mojo.codehaus.org/tomcat-maven-plugin/deployment.html mvn clean install && mvn tomcat:deploy <-- win NuGET only deals with dependencies but doesn't deal with packaging, running unit-tests, running integration-tests, running PMD/CheckStyle/FindBugs as part of your build. All of these things are important for CI/Continuous Delivery. Oh almost forgot this one: JavaFX 2 may be way behind of .NET WPF but JavaFX 2 comes with a tool that can generate installer for OSX App Store (will bundle JRE automagically), Windows, and other platforms. WiX can't do that. I may be ignorant of some of the .NET stuff but as of 2010 - 2012, the last time I used .NET, .NET is still lagging behind Java when it comes to tooling.
