I think the diverging diamond interchange is terrible. Because of the crossover, traffic can only cross the interchange in one direction at a time, so most of the traffic in the interchange is not moving most of the time.
A pair of roundabouts connected to on ramps eliminates the danger of left turns without stopping the majority of traffic most of the time.
A massive overbuilt interchange that cannot function without traffic lights is the opposite of elegant.

I’m not so sure about that. The appropriate use of a diverging diamond is when there is a lot of traffic entering and exiting from the ramps, and some of that traffic can go at the same time as the traffic crossing the interchange in one direction.
