These seam to be fashionable these days. The imitation of a waterfall. Although they look nice and I like to play with the "joystick", I don't like this type of taps. The only reason is water splashing. I prefer taps with aerators which turn the stream of water in many droplets. The perceived flow is higher and the water splashing is reduced.
We had one of the "no aerator" type taps in the kitchen of the house we rent. Albeit not AS NICE. But we are glad the landlord let us change it.
