Nobody has given a definitive advantage to EPR on here, and I do not know of one ... only massive disadvantages. So why use it as the primary thrust reference ? It is not only the increased complexity of the measurement, but also the fact that it requires and independent system to keep it anti-iced ... another potential source of failure.
I have flown with engines from all Western manufacturers, and they all make good products. I cannot see what disadvantage GE is at because it uses N1 .. it is simpler, more reliable and prevents beating. What is there not to like ?
