Here is my take

Yes they are one of the most well known and underrated dinosaurs in the dinosaur media

No, those 3 are by far some of the most popular Hadrosaurs, even if they don’t pop up as much in modern media.

There is no such thing as too much love for Parasaurolophus, Parasaurolophus is love, Parasaurolophus is life

The other two are perfectly rated

Two of those are the two most recognizable hadrosaurs, and Lambeosaurus isn't that far behind
