The answer to 'which is better water heater or' is that there is no simple answer, as the choice between a water heater and a tankless water heater depends on your specific home and hot water needs. Both options have their own advantages and disadvantages that should be carefully considered.
Traditional tank-style water heaters are generally less expensive upfront and can provide a large volume of hot water at once. However, they require more energy to continuously keep a tank of water heated, leading to higher ongoing energy costs. Tankless water heaters, on the other hand, heat water on demand and are more energy-efficient, but have a higher initial investment cost.
