Hello,
I can for sure say RVR and JC, SRKR bhimavaram are pretty great. These colleges have nation wide recognition and among the topmost colleges in Andhra Pradesh. RVR and JC was listed as one of the topmost private institutes in India, with a great NIRF ranking.
You can know about both the colleges, following the links mentioned below-
