I wouldn’t worry about rank or the other things. Which do you prefer ?
Because you didn’t see NY, Ga Tech is safer. But today where you go to school has little impact on where you’ll end up long term.
No bad choice here. Pick one and run with it and congrats.
Ps - is Columbia paying transport ? That’s a cost.
I’d go there. Why ? Free to explore a new and awesome city b4 you maybe go home in four years. But that’s me. You can still root for Ga Tech football. At Columbia, you might …or might not…be exposed to protests - are you comfortable with that ?
Congrats on fantastic gets.
