Cable issue: 360 on VGA or component? If component do you use a splitter?

[BengaBenga]

Question:

What gives the best quality on my LCD TV (Full HD). I can input both component and VGA cables (and DVI, which unfortunately no console supports afaik).

In theory VGA should give the better results, because it's true RGB, which component is not. But I've heard some complaints about using the VGA cable on the 360.

Does anyone know what's best?

I would prefer to use a VGA cable so I can keep my Wii on the component input. I can always use a splitter of course.
