IITK has better academics than other IITs. Also the faculties are better here and if you are interested in research work then IITK is best place for you.

The admission to IIT architectural courses is through the JEE Advanced not JEE Mains. The people who qualify for JEE Advanced have the option to appear for a separate architectural aptitude test conducted after the announcement of the JEE Advanced results based on which the allotment of seats is done there. Through JEE Mains paper 2 you can apply for other institutes like SPA, BIT Mesra etc for the architectural courses.
