That depends on dev current skill in each language. Both languages are very similar. But .net is far better ^^

Comments pointing out that java is open sourced and has multiple libraries and tools written by community makes my giggle XD. Most of .net world is open sourced now. Just check github. Believe or not, but .net also plenty tools/libs, which in my opinion are far better. In .net world there is usually, one outstanding piece of code which has a lot of love from community, while in Java there are sometimes dozens for same thing and it is just personal choice to pick one of them.This sometimes a big problem, because it harder to find employees with expertise of these particular(sometimes very niche) tools your company use in every project.

Eclipse and NetBeans compared to Visual Studio are just advanced notepad. Creating and debugging a new project is just 1-2 clicks. Deploying? 2-3 click and it is hosted in azure cloud.

There is a lot of support from Microsoft Microsoft care. Microsoft listen. Microsoft has program for new companies (bizspark). It gives the access for all MS software for free. As far as I know. Orcacle can only give you a law sue and don't give a damn at all about community. All MS product are based on .net used by millions There is now way it disappear any soon.

Windows Licensing costs comes to none if you host your apps in azure cloud which is great for any size of company, but small and medium benefit most. Moving our client app to azure saves him 30k euro per year.
