Is IIT Kanpur B.S. physics good or should I go with IISER?

Both IIT Kanpur and IISER provide excellent quality education but IISER has a slight advantage when it comes to the quality of research conducted. 

IIT Kanpur 

• IIT Kanpur provides you with the necessary exposure and brand name.
• The students can be seen as more interested in jobs than in research work. The environment at IIT Kanpur is not conducive to cutting-edge research work.
• The professors limit their teaching to the extent that students become excellent employees for outstanding companies.

IISER 

• No compulsory attendance rules yet the classes are packed with students.
• The professors are very learned and approachable. The quality of education they deliver is top notch and students are always approaching professors to get their doubts cleared
• There is great harmony between the juniors and seniors and ragging is forbidden. There are heterogeneous groups of students every year

IISER provides an excellent environment for students who want to become future scientists and contribute to society. It will also open doors for Ph.D.
