Journal Swordless Samurai's Journal: OpenGL Vs. DirectX 2

Ok, So the basic Question I have is simple, OpenGL or DirectX? I Want to begin graphical game programming, and i've learned their is OpenGL, which would include OpenAL(OpenSL) and other Sets to make the whole game, while DirectX is almost self-contained. Now, let's face it, if it's game development, it's got to be Microsoft, so I know i'm going to be programming it for windows. I am going to do it all in C/C++ and i've gotten many people in a passionate debate over open vs closed standards. So I have a real question to all the game programmers out thier... For Windows Game Programming, which is A)Easier, B)Faster, C)Neater, OpenGL or DirectX?
