We have a mullioned window at the top and a mullioned window at the bottom. The increased light yield of mullioned windows is certainly measurable, but in my opinion not necessarily decisive. The driving rain resistance is better with windows with center mullions, but you have a roller shutter against driving rain. There is still the advantage that you can perhaps bring in a sofa with the crane at some point in the future.
