Windows by a mile. The plethora of top notch development environments and tools, and the "just works" attitude of installing and tweaking software makes it my choice hands down. Not to mention everything has a GUI, this in itself would make it the winner. I've developed on OS X in the past, used to have a linux box as my main desktop OS, and I currently develop a project that's targeted for linux and so I develop on a linux VM, and I am constantly amazed at how frustrating the process can be, even more amazing that people actually convince themselves they prefer this to a more streamlined process.
