Hello student, 

Generally, YMCA University, Faridabad is far better than IIIT, Lucknow. When compared, the faculty, placements, education and lot more, everything is better in YMCA than IIIT, Lucknow. Also, the brand name of IIIT may help you that's it and the quality of education is also improving gradually in IIIT, Lucknow with time. Both were good and YMCA is in bit higher than the IIIT, Lucknow. So, be patient and choose the best and it all now depends on where you reside and how much you can afford.

Cheers!
