Hi!
Glad to hear that you have so many good options. But considering everything else you've said, Georgetown I'd assess as the best of the lot. It is undoubtedly an excellent dept, and even though they have 2 comp linguists, I'd say it's more prudent to rely on the strength of the overall department while making assessments. I'm an international student, so my "additional factors" would be different from US students, so I can't speculate. Incidentally, Georgetown is going to be my own school for the PhD beginning Fall 2021 (my concentration is Applied Ling). I am very excited.
Anyway, all the best of luck on your decision, and do let me know if you ultimately choose GU!
