For people that are into style, the aluminum case is a non-starter. Completely clashes with the rest of the outfit in a very bad way, ie. the eye is drawn to the watch to understand why a contrasting accessory has been chosen for this outfit. The steel case with the premium bands don't completely solve this problem; but, they mitigate it a lot. ie you can get away with wearing a stainless steel case + Milanese loop band with a suit and it isn't going to look so strange. Additionally, in the world of watches, the titanium Apple watch isn't even expensive.
