Gas hot water heaters tend to be a lot more efficient than gas cooktops. The flat bottom of most pots and pans means a lot of heat will escape up the sides, but hot water heaters can be designed with this in mind. On pots, I have one that basically has heatsink fins on the bottom to better capture the gas heat, but this is far from typical.

Environmental issues aside, gas is also a pain for installation. Solid pipes are more difficult to route, and leaks are, of course, dangerous. Electricity is dangerous, but it is easier to contain. It doesn’t leak into the air, and because it’s a closed loop, we can measure if it isn’t all returning and shut it off (RCD/GFCI). It also has flexible cables. The downside is that, heat pumps require more maintenance. They’re a vaguely complicated mechanical system, as many fluid systems are.
