@nishant1247 Awesome results. Both are great schools.
What kind of labs/profs are you thinking of working with? It may depend on your goals for computational skill-building. From everything I’ve seen at CMU while visiting for a hackathon last summer, they have some big stuff happening in data science & ML/DL (with even their own department separate from CS), which will definitely rub off in coursework and research. There's also a lot of collaboration with UPitt and its med school, which is enticing on many fronts (new perspectives, data, etc.).
Not too sure about GaTech's program (other than it being well-established), but you probably can’t go wrong with either.
Other than academic specialties, factors like geographical location/weather may play a role in your decision — as a Californian transplant from the Midwest, I will say that warm winters are a lovely privilege that Atlanta shares. I hate to make blanket statements, but Atlanta also definitely takes the cake on city size (population and area) and things to do for fun.
