BITS Goa is better than NIT K/W/T.

• A great factor about BITS is the process of admission is executed based on the merit of the candidates, and not based on the system of reservation which is being followed by many institutions in India. 
• The institution has adopted the curriculum of the courses from MIT.
• The student crowd is very good at BITS. 
• My friend is a graduate of the institution and claims that the infrastructure of the college campus is among the best in India.
• The placement of the institution is also extremely good in comparison with many IITs and NITs of India. The placement statistics of BITs Goa are mentioned in the table below for reference.

Lastly, the choice is yours. You should do thorough research about all these institutions, and choose based on your interests.
