If you're looking for a clear contrast between sense and sensibility, see Edward and Marianne's conversation about dead leaves and dirty roads at the end of Chapter 16!
I think Austen is almost caricaturing the two perspectives -- Marianne's raptures and Edward's practical responses about dirt and roads.
And I always love it when Elinor teases Marianne:
"It is not every one," said Elinor, "who has your passion for dead leaves."
The rhythm of that sentence is so PERFECT, how the narrator's "said Elinor" supplies an ironic pause in the middle to underscore the distance between "every one" and "your passion for dead leaves."
