hmm. I would chose NIT raipur. ECE is a good branch, and this NIT is quite old, so you dont have to worry.
From my experience at BITS, I would also say meeting people from various parts of the country is another plus point. That is something you wont get in a local engineering college.
The only normal reasons I see anyone choosing some local college over an NIT are if your not getting a good branch or the NIT is very new (less than 4 years).
So go for the NIT. All the best! :)
