I only know about Seattle University (SU). It is a respected school and has a very active alumni network in Seattle. You can't go wrong studying at Seattle University. A relative of mine is an alumni of the school and was happy with his education.
If you don't know, SU is located on top of a hill in the city so it is not a secluded campus but more of an urban campus.
Personally, I think both schools are probably on par with each other and your choice is really which city do you prefer and/or which subject do you prefer.
