Cloverleafs also suffer a lot more when merging traffic becomes backed up, since there's no guarantee that the traffic merging on/off will be at even close to the same speed as the traffic that isn't merging.
It turns out that engineers select different interchange designs based on the expected traffic patterns, and there is no one-size-fits-all method.
As a sidebar, my dad was part of the (huge) team of engineers that helped implement the first few diverging diamond interchanges, and so its a fun reminder of him, even if I'm not on a road he had any hand in designing.
