I'm using a suspension seatpost now, removed from a town bike. It's
slightly more comfortable. No idea if it's more efficient. Certainly
heavier, probably lossy unless I balance pedal effort to keep pressure
on the saddle constant. That difference is small at most.

 FWIW, when coasting - especially on rough downhills - my habit is to take some of my weight off the saddle, hoping the "suspension" offered by my legs causes less jiggling of my body mass, so less energy loss.
