I would expect if you look at the big picture, they will result in

the house warm on their return. With a manual stat someone has got
to remember to do it every time.

Occupancy pattern is key I think. If you work varying hours a bimetal
works better. If your hours are like clockwork a digital works
better.

One might argue that if you work varying hours, then remotely accessible
electronic is better still.
