I would advise you to join ETC at IIEST Shibpur and prefer it above EE. ETC has Placements at par with IT and CSE and much better than EE. Secondly, ETC is a really nice branch with balanced Academic Load, you can pursue your interests be it Data Science, GATE/CAT Preparation or be it Research. Secondly 3 Departments of IIEST , namely CSE, ETC and Metallurgy have very strong tie ups with IIT Kharagpur, and you may easily go for Projects and Internships throughout your stay at IIEST. Secondly, ETC or somewhat ECE at many other Colleges have excellent career scope and prospects in the Private, Public as well as Research Sector, and in a vital stream when you talk of Robotics, Electronic Materials or Industry 4.0
