我覺得樓主是時候說說自己的research interest了……
在這類相差不遠的課程之間作出取捨, 估計看:
1. match between the research interest of the student, and the strength of the school
2. location preference: 有多想跳......
vote for CEMFI, also has PhD positions. And the reputation difference in the academia area between these two options are so small that you do no need to take it into consideration.
In Spain, you will enjoy much more sunshine than in Netherlands! And more delicious food. Trust me, given you have no other significant preference, your life quality will be a big issue when pursing PhD. Btw, I think no one cares where you get a PhD degree, UvA, VU, Erasumus or CEMFI, really almost no difference.
