According to a senior of mine who has graduated from NIT Raipur, the institute is better than most top colleges in Bangalore including VIT institutes.

Despite having a soft spot for NIT Raipur, she does not discourage candidates from trying their luck at any other university, including VITs. She, however, suggests that they should get acquainted for measuring progress after completion of the undergraduate degree.

Campus:

• VIT campus is definitely better than the NIT Raipur campus. Although the NIT Raipur has been considerably renovated. 
• The VIT campus will cost around 2 lakhs per year which includes hostel fees as well. Education at NIT Raipur will cost around 0.5 lakhs.

Course:

• The course of VIT will not have any effect on your CSE placement. 
• On the other hand, your coding skills and DS+Algo will have a part to play in your placement. Either way, the effort is required regardless of how much you pay.

Placements:

• By the time you graduate, if you choose NIT Raipur, that is, the institute will pretty much be holding its own among other giants. My senior said two of her batchmates landed a 75 LPA package without paying hefty college fees.
• VIT, being a private college, is known to boost their placement records. In addition to that, they have a management quota as well which goes on to say that not all the best minds will be found there.
• A friend of my seniors had a good rank and went to VIT. He got chosen in three companies. VIT attracts employers in large numbers but they offer packages of only around 3-3.5 LPA.

In the case of NIT Raipur, almost every candidate will get at least one job, in recent years many also bagged two jobs. The ones who have, get a package of 4-8 LPA for the first job, and a package of as much as 16-17 LPA for the second job. Candidates who do not get a second job also land a job with a package of 4-8 LPA. 

Overall, it is safe to say that CSE from NIT Raipur will be a good option.
