Hi, according to NAAC JNTU ANANTHAPUR  has a B++ grade and ACHARYA NAGARJUNA has B grade. The best bet would be JNTU but your needs and requirements might change the answer. The best way to know about the students and faculties is to connect to people through LinkedIn. Below is the link to compare colleges, it will give you an insight about almost everything so you can decide which university suits you best. Hope this helps.
