Candace is more of an antiheroine (female protagonist who displays behavior contrary to that of a hero, or main character). She does play an important role in the show, and though she can sometimes get annoying, she fully deserves her spot.

Isabella on the other hand, was originally only there to be a love interest for the main character, and that's what she is. Though throughout her screen time she has evolved into a heroine with full personality and character. As I recall, Dan and Swampy described her as "the Phineas" of her group, and that there is a whole side of her that the audience doesn't usually see (Isabella and the Temple of Sap). The writers do realize Isabella's potential, and have not forgotten about her (there was even talk of a spinoff for her!), so don't worry.
