Harrison Ford was probably offered better roles based on looks and acting talent, but before Return of the Jedi ever came out, Ford had already been in American Grafitti, Apocalypse Now, Raiders of the Lost Ark and Blade Runner, all certified classics. Hamill, on the other hand, was doing Corvette Summer and The Big Red One. Ford's movies did gangbusters at the box office, not to mention he had managed to land the lead in a new series that would go on to be one of the most successful franchises in film history (Indiana Jones). Hamill's movies? Not so much. He couldn't crack the box office the way Ford could.
