Help me plan out my Early Round [Chicago and Columbia]

I’m not close with that many seniors that have applied to chicago EA so i’m not really sure. I think most people at my school just go all in ED and EA isn’t really considered. My sibling applied and got into Chicago RD. I know it’s super arbitrary to try to judge, but we generally agree that I have a slightly stronger app (slightly higher act, higher gpa, slightly better ecs, rest similar), but I’m worried that they may have had an X factor or hook that I may be missing out on.
