As per the rankings of these colleges, CIT would be best option for you. SSN college would be the best among these for mechanical engineering as its considered as one of the best colleges for mechanical engineering under Anna Unversity. I would recommend you to go through the course structures and placement statistics for mechanical branch for these colleges and then decide.
