You are welcome. PurpleTitan also offers good advice. I think you should gather as much data as possible, then make your own, personal decision. My main point is that these two institutions are fundamentally different in almost every way.
I might caution, however, that you haven’t offered any details on your cost of attendance. While you say finances don’t matter, I would be wary of spending much more $$ to attend a program such as SCU, which is a predominantly regional school. Especially so for a potential business major, where cost-benefit analyses will inform your thinking in school, and thereafter. You might also, as a business major, consider brand appeal. UW has global appeal. I can’t speak much to SCU, but I doubt its brand penetration is similar.
Lastly, if you are quite serious about academics, you’d likely consider more than just marketing courses; also factor in economics, other business, communications and the like. In other words, I’d recommended availing yourself of resources in order to enhance your career prospects.
