You don't know what you are going to start with a thread like this... all out flaming, basicly. With that said, here is my answer.

The best OS is the OS you like the best. If you like Windows, and what you can do/programs for it, use it. If you like Linux use it. If you like something else, use it. There really is no "best OS" just opinions on what the user likes. I suggest you give a few of them a try, and see which one suits your needs.

Peace
