is it worth it to join bottom tier sororitys

Im a junior who rushed this past fall but I got dropped by all houses but the bottom two speaking in "tears". Is it worth it to join those houses and put the effort? Im a pretty social person and my friends are mostly in middle - uper tier sororitys, I wouldn't consider myself nerdy or etc and im not awkward personality wise. Do you think I would still fit in with the girls in lower sororitys? Is it even worth it for the time commitment to join?
