Hello,
.
Both the colleges are well rated. I cannot find any difference in the colleges. These colleges have equal rating, equal reviews and provides a best education. But the difference is IILM provides only, PGDM and FPM courses, where IRM provides B.e, M.e, BBA, PGDM , MBA and BCA courses.

IEM is a bit older established College, both the Institutes are private and has accreditation of NAAC A. You can opt any of the institute, both are best. Can have a look about College details from the below provided links,
