For engineering, VIT-Vellore is better for all the courses and it has excellent placements. For arts and science VIT Vellore is good but I don't have any idea about the placements for those courses.
Stella Maris College is widely preferred for those who scored well in the board exams and for arts and science stream. It is a popular college in Chennai and has a good reputation.
If you want to go for arts and science in Chennai with a moderate fee and good education then prefer Stella Maris College Chennai. VIT Vellore is best for engineering but I have no idea about arts and sciences.

It depends on your priority like package, company, etc. Both the colleges have good brand value.

RV College is the best option in this lot because of the low acceptance rate and the quality of the students.

All the best.

I might sound harsh, but I will be honest. Recently most companies are going for core companies. However, it might be in all the colleges, but now most of the companies ask for mechanical engineers instead of automobile engineers. Even core automobile companies like Maruti Suzuki prefer mechanical engineers. So, I would suggest, that if you are too much into automobile, take mechanical engineering and later take up automobile engineering for your Masters.

For Civil Engineering, Institute of Technology, Nirma University will be best from these two institutes in every aspect of training, education and you.
Best of Luck!
