I think vector (SVG) is superior when it comes to logos and icons. When a vector is rendered it is done in the context of the system used. For example sub-pixel rendering uses the information of the display.

In my experience a SVG logo rendered in a browser always looks much better than a pixel variant.

The only thing you can say about 'pixel perfect' is that you know for sure that pixel X,Y uses color C. But that doesn't mean you know how it will look on screen. Or how it will be positioned.

Also in this age of very high res screens I think vector is the way to go.
