So I'm a first-year student at UWSOP. If you can give what you think are some pros and cons at each place, I may be able to help you out. You can also PM me with any questions you have.
The pharmacy program is really well known here, and pharmacists in UW have a lot of options, in part because of UWSOP's efforts. I like how the program is set up, for the most part. The first year has been a bit light, although I did 6 years in a grad program before pharm school, so I may be a bit biased. And UWSOP is really interested in changing and improving classes so we get the best education possible.
The one negative I can think of (which may be the case at UM, too) is that we're a little light on business classes, but that may or may not be an issue for you. And I think you can take some business classes as pharmacy electives.
Hope this helps!
