Early Decision Choice and Strategy

tough question and the answer will depend on your personality type. But if it was me, and I loved all 4 equally, and the prestige difference was minimal, I would ED at the 90% one and be done with it all.
If there is a significant selectivity and prestige difference, then that does create the risk of buyers remorse- oh, man, I should have tried for the harder one, now I will never know…you don’t want to live with that.
