both are good schools. 2 major considerations are board pass rates and cost. If you live near one and can live at home, i would do that. Board rates are similar I think.
Assuming you have to move for both, look at program, facilities, experience, and what piece of paper you want hanging on your wall after.
I have recently chosen ICO, over NOVA. I have not applied to Pacific, but i will tell you why ICO is my first choice regardless.
ICO's facilities are very good. nearly 40 exam lanes. The Illinois Eye Institute sees a huge amount of patient diversity compared to other clinics. The residency programs are top notch, even though i don't know if I will do one. Chicago is a pretty cool city with good public transportation. Lots of young people. The residential complex is right across the street. ICO is set up to make the transition to a new place easy. There are scholarships and work study opportunities. Overall, it seemed very professional when i went there. Everything is laid out for you, cost, what you learn, what is expected, in detail, unlike some others.
I think you would see more going to ICO. ICO is on quarters, so more tests, but more breaks. I have been told the program is perhaps slightly more rigorous than some, but I have no first hand experience to substantiate.
I think both schools would be good, but for me, ICO's program is a little more polished than some. I think you might have to put a little more in, but would also get more out. I know my values are different than yours and as cliche as it is, try and think of the experience you want to have. Some don't care about patient diversity, or want to live in a big city.
Good luck. BTW, I shadowed an OD that went to Pacific, she said it was a good program. She then went to Chicago to do her residency. She said you see a lot more diversity in chicago.
