See both this NIT's are new NIT's. But both these have great potentials to come up in contrast to the top NIT's. I would say if you want to pursue course in UG engineering then go for NIT GOA. NIT GOA have better infrastructure as compared to NIT PUDUCHERRY. It has good number of well experienced teachers and have ranked in top 50 by NIRF. The college have good lab work and the curriculum is also very relevant to the industrial need. Also NIT GOA have good placements ratio compared to NIT PUDUCHERRY. The difference between this two is very slight but if you have to choose then choosing the best is the right choice. As per the information NIT GOA is better than NIT PUDUCHERRY.

*I would like to recommend you to do a research by yourself and then only take decision.
