I got accepted into Midwestern and Western and have decided to go to Midwestern - both are private colleges, so tuition was roughly the same for me
There were several factors that made me decide on Midwestern:
Cost of living: from my visit for the interviews and a cursory search for apartments, Midwestern was a lot cheaper
Environment and Weather: Aside from summer, AZ has almost perfect weather year round
Curriculum: From what I hear, Western was pure PBL whereas Midwestern appears to be hybrid which suits me better
Academic system: Western=Semester, Midwestern=Quarter - I've been on the quarter system since freshman high school and I HATE how slow semesters are.
Dedicated facilities: Midwestern is going to have brand spanking new buildings, equipment, and etc.
Etc. etc. etc. your miles may vary on your personal situation/school
Just do be mindful that as a new school, Midwestern still has a few kinks to work out. If you look at Western's statistics (the last new school) their first graduating class only had a 78% pass rate for the boards - which steadily rose each year to around 97% or so last year, which is actually one of the highest among the vet schools. Don't even worry about accreditation as it's really not that big a deal (for comparison, UC Davis lost theirs a few years back) - as long as you graduate you're going to be allowed to take the boards <-- this is the stickler for me as I look at Western's first class statistics... but the majority did pass
If I got into my instate though.. (UC Davis) that's what I would've picked - not even because of its reputation, but simply because the tuition is almost HALF that of Midwestern... sigh... I'm looking at a mountain of debt when I graduate D:
