I originally went into getting a new water heater with the expectation that I would do tankless since they are more energy efficient. However, it was going to be cost prohibitive to run a new gas line and you should never ever get an electric tankless water heater. The hybrid tank water heaters are almost as energy efficient as tankless and I really like this one from Rheem. It has a companion app that I can use to change settings, look at how much energy is being used, and even set to vacation mode so it's not keeping 50 gallons of water hot while we're away. The side benefit of using a compressor to heat the water is it dehumidifies our garage at the same time.
