Tankless (On-Demand) Water Heaters are much more efficient than tank systems; up to 25% more. They also have a much longer operating life than tank heaters. Most tank heaters last less than 10 years, whereas tankless last up to 20.
The difference in unit lifetime, plus the savings in operating costs, pays back most, if not all, the total up-front investment in the heater.
The large difference in up-front cost is due to the different scenarios of a) purchasing a new tank heater compared to a tankless heater vs. b) replacing a functioning tank system at the higher end.
