My experience...
So I went out and ordered the Stainless Steel Link Bracelet from Apple. After trying it on at the Store, I really liked it and wanted to stick with the Apple branded one. I received it the next day and put it on my Aluminum Series0 watch. Truthfully I do not think that it looked as bad as some make it out to be. It is somewhat noticeable but only it you are focusing on it. It is something that I could see myself sticking with.
I also decided to order a Stainless Steel Series2. Now of course the link bracelet looks better on the SS watch. But I am mainly writing this to say how much nicer of a watch the SS looks over the aluminium sport. The SS looks like a much more classy and refined watch and I feel even with it being shiny, it does not stand out nearly as much. I never thought there would be much of a difference but it really is night an day. It is unfortunate because I don't think pictures on Apple's site really do the SS justice to show how much nicer of a device/finish it really is. Every band I have looks much better on the SS version, including the Milanese and the Brown Classic Buckle.
Moral of the story, yes the SS Link can look OK with the Aluminium Sport watch, but the Stainless Steel watch is a much more beautiful piece of hardware.
I read something one person wrote before that said something like the SS Watch looks like a much classier timepiece and the aluminum looks more like a toy. I kind of really do agree.
