I second what @Thorsmom66 says - you just never know. Even the Vandys of the world are tough - but you’ll likely get into a top 30. Or you can go, like so many Ivy types, to a public with merit and crush it (assuming you don’t qualify for need aid)…so you’re not paying $80K.
To answer your question on REA, the answer is yes assuming:
It’s hard to tell but on Harvard’s website they say there’s no advantage but there does seem to be on on Princetons although they don’t say it. It depends on your match schools - because if they are private and you want to apply on an early action, then no - don’t use restrictive. If you are not applying to privates with early action (like a Miami), then roll the dice. At the next tier private schools, you’ll want to apply early to those that offer - and if that’s the case, you can’t do early action at Harvard/Princeton.
No matter what - make sure you have targets (the Rochesters of the world, maybe Emory, a Wake Forest, etc.) and safeties (which could include Miami).
btw - Ga Tech and UGA Honors - both OUTSTANDING.
Good luck.
