Missing UI Element: Magnetic Radiobuttons

As per Mitchell Bernstein's suggestion, I wanted to try how the Orbit Switch would work if it was closer to traditional radio buttons. These have the advantage of clearly showing if you picked option A or B. Maybe the sliding 'Today' label is a little odd. The controller will have to take up more vertical space to allow you to easily tap either option.

Which do you prefer, these Magnetic Radiobuttons, or the Orbit Switch?
