Hi Joey, reputation wise UW and UM are both very decent schools, though arguably UM is more well-known to international applications and employers. Besides that, have you compared the curriculums of the two programs? which one is more aligned with your career trajectory? While UM's program is housed under engineering, from I've learned in this forum it seems students have quite some access to Ross which is a plus given its reputation. On the other hand, UW's program is under Applied Maths and also taught by top faculty from Statistics, both of which are top tier as far as grad school is concerned.
