We have never had a chain fall off or jam. For the ineficiency, I'm not sure. Gears can be just as ineficient if not meshed and aligned properly. As for space and weight, I can really debate that. But we like chains and sprockets just because of the simplicity and robustness. It is so easy to set up a chain drive with simple tools and make it very effective and robust too.

Our robot:
2 Drills
2 Chias
-- All sprockets carbon steel #35--
4 10T
4 32T
2 35T
2 48T

42 inches in total of 5/8 keyway shaft

Very heavy but if you saw our robot in action at Phoenix you wouldn't complain about the weight.
