I had an electric tankless when I lived in a condo high rise without gas service. My panel had space but I had to upgrade with wiring to the unit, which was almost as expensive as the heater itself. For tankless, gas or electric, it's a game of temperature delta and flow quantity. In the winter when the water coming in is colder, you'll be unable to have as many hot water uses happening simultaneously as you do in the summer. Depending on the unit size, during the summer you might both be able to take showers in different parts of the house with the dishwasher running. During the winter, you might only be able to do one of those at a time. Otherwise you get lukewarm or even cold water.
For my condo it was a good solution as it freed up a large amount of closet space and it was just me living there, so the only time water temperature was ever a problem was in the coldest days of winter. I wouldn't go with an electric tankless unit in a house, especially with multiple people living there.
