I can see what you're saying Bonobo but it all depends on perspective again. You gotta be pretty far west to see the Aon Center peaking over River Point/150. Like way out past Ashland, and Salesforce will be ~100' taller.
This shot from Green Line/Ashland is a couple years old now but this building will be every bit as tall as Trump from that distance and Aon isn't visible at all. Even Vista will be entirely blocked by River Point.
