You left out one very good possiblity: a gender-based difference.
The one with the large crest could be the male, and the one with
the bumb could be the female.

Actually, there is even another possibility - growth phases.
The one with the small bump could be a juvenile (look at the
difference between juvenile and adult Corythosaurus - the
juveniles used to be placed in a different *genus*, Prochenosaurus).
