Oxford DPhil Vs Georgia Tech MSCS

[vikul]

I have got admit from DPhil in University of Oxford (funded) and MSCS in Georgia Tech (not funded, but can easily get TAship). My goal is to do PhD (in case I go for GaTech, I will definitely apply for PhD) and then go for an industrial research. I have a bachelors degree from India.

Can you please discuss the following points:
(1) Chance of working in US/Europe (after PhD completion)
(2) Reputation of the degree
(3) Oxford has 3.5 yrs program while in US it will be 5 years.

Thanks!
