I would suggest you to pursue MTech from DTU CSE. DTU is one of the best Technical Institutions for CSE in Delhi NCR after IITD. The CSE Department has strong faculty, infrastructure as well as good Placements for MTech. Being located near Technology and IT Hubs of Delhi NCR provide huge scope and impetus to training and placements.

IIT Jammu is still in its nascent years and DTU CSE has a much stronger Academic, Professional and Employer Outlook.
