They should not differ appreciably in light output. With the front, you can only tilt one sash and only open the "second" sash after the "first" sash. With a webbing/middle mullion, you can tilt and open both sashes independently of each other. With the fore-end you can make one large opening, with the remainder you can make two openings next to each other.
