Dear aspirant,

Specialisation courses are much better than just normal courses as there you would get to learn what you want to focus on and study . Faculty wise software is very good, teachers are very cooperative and well experienced.

Although if Big data course is there in SRM University you should take up that as it is very demanding in the industry right now and even after four years data generation won't stop and data analysis would never be unemployed.

Rest is upon you what you feel like and have interest in.
