A company that is famous for being metrics driven and having teams that optimise for their own metrics is Facebook. You can tell that the product has "seams". Each page and widget feels like it was individually optimized and then stitched together. Overall it somehow feels off.
Apple puts design on top and has a kind of dictatorial veto over all aspects of the product. Hence products made by Apple feel seamless and cohesive. They are also more polished because when you solely rely on metrics you make it as good as it needs to be and then stop.
