Which is the best university, Sathyabama or Karunya?

I completed my B.Tech from Karunya University, but I can tell you a bit about Sathyabama as well. 

Sathyabama offers decent academics, good quality mess food, and good placements. But it is located very far away from the main city (Chennai). Moreover, its infrastructure is not up to the mark. Its biggest disadvantage is that students of the opposite gender are penalized for even interacting with each other. Boys and girls are separated right from the counseling process. 

Karunya University is located in a beautiful and serene landscape, and surrounded by mountains on all sides. It has good infrastructure and quality education. Its placements are average. Its hostels are good, and the mess food is good as well. It has strict rules only for first years. It has a diverse student population, with students from other Indian states and countries as well. Hostel is mandatory for B.Techs, but not for some degrees. 

It charges high fees, and some of its departments have poor placements. The rules are very strict about clean shaving. The faculty takes out personal grudges on students’ internal grades. Most of the hostels are located far away from the campus. 

According to me, Anna University affiliated colleges are much more affordable for B.Tech studies. So you may consider them instead of these two universities.
