For a SFR, or a sub-metered multi, I'd stick with traditional hot water tanks. I'm partial to gas, myself.

For 2-flat on up with a common hot water source, I'd actually recommend having a tankless feeding into a traditional tank. The tank will keep the water hot, and having the tankless between the tank and the supply will help ensure a virtually "endless" supply of hot water, even if baths/showers, dish washers and laundry are all happening at once.

My $0.02 ...

AO Smith HSE-SGS-006 is a great choice for you. This BEE 5 star rated water heater has extremely low standing loss of 0.28 units/24 hours. Because it has a 3000-Watt heating element, the heating of water is quicker than most normal water heaters in the market (please note: higher wattage in water heater does not mean more electricity consumption but faster heating. Electricity consumption depends on volume of water used). This water heater has AO Smith’s Blue Diamond Glass Lining for corrosion protection of the tank and the heating element is also glass coated for corrosion protection. The heating element is also made of stainless-steel core to protect it from corrosion.

From the 2003 IRC:
"M2005.2 Prohibited locations.
Fuel-fired water heaters shall not be installed in a room used as a storage closet. Water heaters located in a bedroom or bathroom shall be installed in a sealed enclosure so that combustion air will not be taken from the living space. Direct-vent water heaters are not required to be installed within an enclosure."

From the 2003 IMC:
"303.3 Prohibited locations.
Fuel-fired appliances shall not be located in, or obtain combustion air from, any of the following rooms or spaces:
1. Sleeping rooms.
2. Bathrooms.
3. Toilet rooms.
4. Storage closets.
5. Surgical rooms.
Exception: This section shall not apply to the following appliances:
1. Direct-vent appliances that obtain all combustion air directly from the outdoors.
2. Solid fuel-fired appliances, provided that the room is not a confined space and the building is not of unusually tight construction.
3. Appliances installed in a dedicated enclosure in which all combustion air is taken directly from the outdoors, in accordance with Section 703. Access to such enclosure shall be through a solid door, weather-stripped in accordance with the exterior door air leakage requirements of the International Energy Conservation Code and equipped with an approved self-closing device."

The concern isn''t the water heater itself, but the source for combustion and ventilation air.

the explanation that was explained to me was the exhaust fan in a bathroom may create a negative pressure situation. in order to equalize the pressure, the fresh air may want to enter the room through the largest opening available, which would be the b-vent opening, which may cause a backdraft situation. A direct-vent or power vent exhaust system may be your alternative choice.

The IPC commentary explains: ... In small rooms such as bedrooms and bathrooms, the doors are typically closed when occupied.
The potential threats include oxygen depletion, elevated levels of CO and other combustion gases.

Basically
For the same reason a fireplace or a warm-air furnace may not be approved for installation in a bathroom or bedroom, combustion air.
