I don't know whether the Roorkee university is more difficult than IITs or the other way around.
In the past when Roorkee was an independent university, its entrance exam was next only to the IIT JEE but that does not mean that it was close to the JEE in terms of degree of difficulty. It was the second toughest entrance exam in India but the gap between the IIT JEE and the Roorkee Entrance Exam was vast. That's all.
