You can make your choice as per the information below. In my opinion  VR Siddhartha is better.

CSE IN GNA: 100% placement guarantee because GNA group has a reputation and good links with the other industries as well. All the industries of GNA group are automated. They are also given placements to their industries. Wherever they give placements, you will never work in a static position. They will give the placements where you can grow your career.

IT IN VR SIDDHARTHA: Placements are good enough for CSE and IT students. Almost 100% placements are achieved. Students get placed in good companies if their knowledge is good enough as per the company's requirements. We can get placed in some good companies like TCS. The highest package offered for a student was 11 Lacs per annum.
