I ended up not getting funding and will be turning both down. I care more about security in part because it’s easier to jump into IO at a more established stage in my career than security.
I’ll apply again next year with a years work worth of savings and hopefully more aid.
Hello! I'm faced with the exact same choices as you too. It might boil down to career destination. I am intending in a security/IO career so SIPA makes more sense for me, but because GT has such a strong connection to the USGov, it might be a better option for you? PS. Did your financial aid offers come in with your decision letters? I don't think I received mine yet...
