Tankless water heaters suck and they don't really save money.

That's an inaccurate generalization.

Technically, tankless water heaters "flow", not suck.

As for saving money, that depends on the application. If you use hot water
regularly throughout the day, you probably won't notice a major difference
compared to a tanked model (other than the hot water never runs out). On
the other hand, if you have a cabin or rental unit that can sit empty for
days, you'll save money by not heating water when no one is using it.
