A glide lasts longer than a DFCO, but we are talking very short glides here. I would be in and out of gear or clutch down and clutch up so often that the trip would be uncomfortable and hard work. And as I won't use engine off coasting the engine is burning fuel while in neutral anyway, so we are talking maybe 15 seconds at 300 mpg against 10 seconds at 9999 mpg.
When traffic is not an issue I use conventional Pulse and Glide, albeit with the engine running while I am coasting.
