I believe you should prefer Engineering Physics at IIT Bombay over NIT W CSE. Engineering Physics is basically a Engineering Research branch and deals with Physics in Engineering and Application. As far as IIT Bombay is concerned, you shouldnt have any issue regarding Location, Faculty, Infrastructure and Research Facilities. As far as Placements are concerned opportunities in Core Physics sector seem bleak with many students joining Samsung Semiconductor, TSMC, LAM Research and some other companies like Applied Materials and Intel. But many students opt for pursuing Masters or Doctoral Degree post Undergraduate from Faculties of Physics in top US Universities like Princeton, UC Berkeley and Stanford. Besides this IIT Bombay has excellent placements as far as non core sector is concerned and you can always find high paying opportunities in Software/IT/Finance/Consultancy, etc. Perhaps I believe at this Rank you might find other Core or Circuital in many other Top IITs and can also consider them.
