ED/REA is extremely personal OP. Fundamentally some people are very “what if” oriented and for those who would always wonder it makes zero sense to apply anywhere but their “dream” school. Otherwise really aren’t quite so fixated on one specific school, and value highly an early decision. My daughter was very much in that camp. She was enamored early with Stanford, but watched every single year as the tippy top academic students (including a good friend who’s application we knew well: valedictorian, 4.0 unweighted, 36 ACT, full IB diploma and fabulous ECs) get turned down and Stanford would take 1-2 of our excellent athletes with good academics. You see it often enough and you get a bit jaded and she ended up not even applying to Stanford as she saw it as a wasted application.
ED rates are certainly overstated with legacy and athletes BUT I will say two things. Two adcoms of top 10 schools bluntly stated it gave a bump to students and if you look at how private schools advise their students, I think ED is beneficial outside of the top handful of schools - most actually have REA and I DON’T think it helps with those.
Wharton M&T was never on my kids’ radar so no clue if it will be a meaningful bump or not. Best of luck to you - it’s a tough process - make sure you’re continuing look and find schools that excite you whatever decision you make for EA/ED.
