Hello,

First let's talk about the difference in campuses in IIT Delhi and Roorkee respectively.

Both IITs provide excellent faculty, infrastructure and transportation facilities thus weighing one over the other would be unfair. But if I go with rankings then IIT Delhi would be the better option since it provides a lot more support for budding researchers and has better placement records than Roorkee campus.

So for a B.Tech or M.Tech degree, go for IIT Delhi.

Hope this helps.
