Hello Ravinder,
Look I have not been to either of them and without hurting anyone,and no criticisms,I personally think that Chitkara is one of the best private university in North India.Its higher studies, infrastructure and  facilities for students are really good as I checked every minute detail on different sites on Google.Even the Industry Exposure is really established very nicely. Infosys, Wipro, Newgen, Persistent, Capgemini, and much more are visiting the campus for recruiting its students for its engineering programs.

Best wishes!
