Pursue or Boulder for aerospace

I just got off the waitlist for Purdue and got into engineering first year. I'm already committed to CU Boulder but am now thinking of committing to Purdue instead because it's 7 ranks higher for aerospace. The main thing holding me back is that I really like CU Boulder's campus and have literally done everything for the school like housing application and scheduling my orientation. Another factor is that there aren't any more tours available for Purdue so I'd either have to go there on my own time without any sort of tour or just commit blindly. Any advice would be appreciated because I'm really on the fence.
