Is and Xbox 360 with an HDMI output and one with blue green red HD component cables look the same on HD TV?

I have two xbox 360's, one with an HDMI output and one with the hd component cables, and use them both on my 1080P samsung, and I got to be honest, I do not see any difference at all. It looks exactly the same, in fact sometimes I think one looks better than the other! Why do people make such a big deal? Can I have some honest feedback from people that know what they are talking about. And please don't just be a creep and say HDMI because you have it and its the cool new thing, I have both and they look exactly the same. Can I have some facts please? Thanks
