Its like every other product, isnt it? Its what you value, or you like.
I hate noise. Thats why i disliked the v stream touring. It did block wind, but my height, my helmet, my whatever made it noisy and i hated it for that. The adjustments also complicate ratings, too..Not all screens work well in all three positions.
Also, with this bike, the screens are cheap, and simple to change. You dont need to be stuck with just 1.
