On the road the horn is often used sprinting. Personally I cannot sprint anywhere near as effectively with the "new" form of saddle. It isn't new anyway, I've seen wide seats with the horn chopped and duct taped for decades. It may well be a good design for commuting, as long as you don't require as much control for your riding style during your commute. When you chop the horn from an ultra plush/wide "comfort" seat often the seat will flex more than its design intended, giving the springs in the rear a more dynamic role while you pedal. Depends on the sort/quality of comfort saddle you've modified. So nothing new in the dynamic department either.
