A chain drive is about as efficient as any drive system ever invented. Gears offer considerably more friction and hence power loss.
The gear's advantage is in durability. It won't suffer chain stretch, and if robust enough and designed properly,will outlast a chain drive and require much less maintenance.
Pick your poison.
Probably imo the gear version advantage is NOT durability. Because the large gear is made out of reinforced PLASTIC.
Since the h219 chain is used in gas engine motorcycles and go kart transmissions as well in much longer length it in ebike short length will probably be strong enough for ebike demands and stronger than the plastic gear.
A spare part replacement cheap plastic gear is not expensive though around € 19 . About two times as much as a h219 reinforced kmc chain .
