Eli or Eliot and Aurora or Amelia?

I am pregnant with twins and we have narrowed it downto these names. We have two children already, Victoria Mae (Tori) and Delilah Marie (Lila). So do you like Eli better or Eliot and do you like Aurora better or Amelia. We know Eli is a nick name for Eliot, but we don't know which one sounds better for a teen and an adult. Which ones do you like better? Te girls middle name will be Madison and the boys middle name will be Matthew.
