Here are some details about both these colleges-
VSSUT holds a strong reputation in Orissa, but CET isn’t that popular. One reason being that there are plenty of Engineering institutes in Bhubaneswar. VSSUT offers better placement prospects than CET. Even though CET receives more companies due to its favorable location, VSSUT receives more job offers.
VSSUT is quite old, and has a rich legacy. CET is also old, but comparatively new. The location of CET allows easy access to coaching centers, and offers more facilities for extracurriculars.
Both have their own advantages and disadvantages. You can choose between the two based on your preferences and goals.
