UCLA vs Minnesota MS Mechanical Engineering

Hi i’m newly admitted to UCLA and Univ. of Minnesota twin cities for MS this fall 2016.

I’m actually in trouble choosing of the two.

The field in which i’m interested is Thermal fluid and energy conversion within heat transfer.

As my final goal is Ph.D, direct passage to the doctors is my first priority.

In terms of Qualifying Exam pass rate and ease of transferring to doctoral program, what is the most wisest choice?

Thank you for your time and I hope there’s any information about the problem.
