ICO Vs IUSO

So I thought I was totally set on going to IUSO, but now I recently got accepted to ICO and questioning everything. The schools do seem to have almost a completely different experience so it is hard for me to choose. There doesn't seem to be many opinions on IUSO here also so any info on that will be helpful.

I am mostly focusing on Research Opportunities, Externship and Residency opportunities and a solid speciality contact lens education. Also anything about student life, Bloomington...
