After last year's Cubido C# Pirates Programming Competition I consider entering the Catalysts Coding Contest this time. That one is about implementation speed, so I was wondering which development environment to use. Most of my programming lately has been in C#, so Visual Studio would be a natural choice. But I consider Eclipse to be a more productive IDE. And there is still the option for a real radical approach - applying LISP for example (oh well, two months left for intensive LISP training then).
