Silent Hill marathon info!

Hey guys again, so today I got Silent Hill 4 and uhm yeah I´m wondering a thing here there are some ways to be playing it if we start with the order of the release of the games we have this:

Silent Hill
Silent Hill 2
Silent Hill 3
Silent Hill 4
Silent Hill Origins
Silent Hill Homecoming
Silent Hill Downpour

or should I play it in the story wise order it should be something like

Silent Hill Origins
Silent Hill
Silent Hill 3
Silent Hill 2
Silent Hill 4
Silent Hill Homecoming
Silent Hill Downpour

So which order should I play it in?
