I would say it's a trade off...
FG: There are times in the flats (especially) when you can reduce your input and maintain the same speed due to momentum. This DOESN'T work when you are pushing uphill and going downhill you are spinning to keep up.
SS: Coasting in the flats, coasting down the hills. How much energy does this save vs. the forward momentum you pick up on the flats in a FG?
I don't know but both are fun in their own way. It's been said before but ride your bike and find out what you like! I ride one bike FG and one SS and I probably wouldn't change the set up of either because I like the variety of both.
