Frankly, I have not heard of UBA till I came to Argentina. For that matter, I have not heard of any Latin American Universities... I'm quite ignorant.
Not sure if the following ranking would help, I am sure there are plenty of good and value for money schools in the US or Canada or UK you can choose from. Even might be easier for you to get employment from these countries having studied there and have the time to look for work... In this day and age, always good to have international experience. If you are a US citizen, may be good to have post grad experience in Asia... and so on....
