Hii,well its depend on you which you like as per my opinion both the colleges are equally good and have almost same reviews by student passed out of the college.There are excellent placement opportunities available in both the colleges.There have been 100% placements for the students studying at KLU as well as Vignan University.
But the main thing is that you will have to put some efforts in studies, and you will get path to success regardless of which college you study.
Opportunities are huge, but students should know how to utilise those and if you are smart enough then you will do great anywhere.
