The more power per year a device consumes, the less energy efficient it is, making it more costly over time.
A direct drive motor has no belt and pulley. This means it wastes less power in friction, are less prone to breakdowns and have longer lifetimes in general. They are able to operate more quietly and with less vibration.
Front loading machines are good as you can use the space above and sometimes stack a dryer on top. In general front loading machines use less energy, using less water by only partly filling the drum and obtaining higher spin speeds which clean without requiring as much heat.
The device is designed a specific way so that it can be built into a cupboard.

Machines with a load sensor can weigh the load and adjust settings accordingly. This means you don't have to feel as guilty about doing a smaller load as the machine will use less water.
More weight capacity helps if you want to wash something heavy like curtains. A traditional household machine can hold around 6kg, so with a machine much bigger you may waste energy using it when only half full.
With a lower noise level for washing you can worry less about disruption and may be able to do a wash at night or while reading.
During a spin, machines can get quite noisy. With less noise the machine is not as distracting and you won't be restricted to using it at certain times.
