Just as I thought I made up my mind and chose IESE, I heard from ESADE about the scholarship: they are offering me 50% of the tuition fees...which is great of course except i have to think and decide again

I asked IESE about the total coverage of the scholarship they offered and it was less than I thought it would be. So, at the end this is the amount I have to pay if I choose either school:
IESE - They are giving 12,500 USD which is like 8000 euros, as a scholarship. So, I have to pay about 56,900 euros if I choose them.
ESADE- With the scholarship, I only have to pay 28,500 euros (which is half of IESE's payment)
Now, I have to decide if IESE is worth giving 28,500 euros more?
What do you guys think? Is anyone in a similar situation??
p.s. and of course I have 1.5 weeks to decide, which is never going to be enough
For HEC, I didn't apply to the MBA program, I applied to Msc in Management which is ranked as the best msc in management course by financial times. As it is not an MBA, most of the students who have applied are my age or even slightly younger.
But you are right, HEC is very well-known international brand, which makes the choice even more harder
Forgot to add:
Thank you
