Frankly I think a big part of the perception that the stainless steel model is superior to the aluminum is that it costs $200 more. If there were no cost difference, I do think a lot of people would perceive the aluminum to be just as high-end. If prices were reversed buyers would most likely see the stainless steel as the lower-end model. Bottom line: stainless steel is preferred due to price. If both aluminum and stainless steel were priced the same, which would you prefer? As prices become more uniform, I believe they will be priced the same. For me, I would prefer stainless steel if it was matte but I'm not a huge fan of a mirror finish on a watch. Although I am getting a bit tired of all Apple devices I have being aluminum, I would go with aluminum regardless of price.
