All the colleges can be good for a student, if he/she focuses on their studies. It's not the college that matters, it is the student’s hard work that makes a difference. 

Out of the two, LNCT is preferred more than the other colleges because some faculties of LNCT are brilliant and resourceful. They are cooperative and highly experienced.

If you think going through a revised copy of what the teachers taught will help you during exams, you are completely wrong. You as a student need to work on your academic skills, communication skills, presentation skills, etc. Teachers can provide you with the basic guidance but in the end it all matters on your hard work.

According to placements also, LNCT is taking all the points and is a decent option as LNCT has a placement rate of 75-80% especially for the students in the CSE and IT departments. Therefore, opt for LNCT without any further thoughts.
