I use that cape and it's great. Yes, it catches the wind, but you need to catch as much wind as possible to evaporate your sweat in the humid air which accompanies rain.
With fenders my feet stay dryer than walking around with an umbrella.

what's the advantage? It won't keep you as dry.
On the contrary, rain wear is a careful balance between speed, rain, and sweat. A cape compromises speed, but is in my experience the only thing that can keep you dry from both rain and sweat.
