Hello Akshay,

Below I have provided the important details regarding both the colleges - 

SJB School of Architecture and Planning : 

• SJB School of architecture and planning is a private college and was eshtablished in the year 2013. The college has faculty about 31 people. 
• The college is affiliated to Visvesvaraya Technological University.
• The college offers courses like B.Arch and M.Arch. 
• The college has the facilities like boys hostel, girls hostel, gym, library, cafeteria, sports, medical/hospital, guest room etc. 

RNS School of Architecture : 

• RNS School of Architecture is a private college and was eshtablished in the year 2017. The college has only 7 faculties. 
• The college is affiliated to Visvesvaraya Technological University.
• B.Arch courses is offered by the college. 
• The college has facilities like boys hostel, girls hostel, library, sports etc. 

Now according to me SJB School of Architecture and Planning is much better than RNS School of Architecture. The former has better facilities, better experience in teaching. Whereas RNS School of Architecture is a very new college (eshtablished in 2017) and it would take some time to make itself stable and to gain recognition.
