How do Elinor and Marianne Dashwood’s romantic relationships differ?

In Jane Austen’s novel Sense and Sensibility (1811), Elinor Dashwood is prudent and discreet (she personifies “sense” in the book’s title), and she forms an attachment with Edward Ferrars. Marianne Dashwood is open and enthusiastic (representing “sensibility”) and is initially infatuated with John Willoughby before making a sensible marriage with Colonel Brandon.
