By all means visit if possible. My grandson's experience parallels Texan in MS's DS with USNA. Grandson attended USNA's summer session, loved it and applied to USAFA as a 2nd choice. We're from Arizona so he did not visit USAFA initially.
Upon receiving appointments to both, he decided that he should at least take a look at USAFA. He did so, coming away very impressed, not just the campus but what AF had to offer. He made a 2nd trip to USNA and in the end, accepted the USAFA appointment. The visit changed his mind. He just finished his first year and has absolutely no regrets.
You really should visit, listen to what AF offers, ask questions, and then you can compare. It is a big decision and while any one of the SAs would be a good choice, you should determine which SA and which service branch is the best fit for you.
