I call your cynical and raise you ironic since u only have 11 posts, tangential since the OP asked about prestige, and narrow minded since some people choose based on criteria other than location.
to OP: Prestige-wise Michigan is considered to be one of several truly elite programs of anesthesia. It's also a ~ top ten medical school and a top 20 hospital. Thus it'll be very prestigious to lay people, general medical people, and anesthesiologists as well. Wake is considered to be a fantastic program as well in the anesthesia world, though I don't know if its reputation outside of that realm extends beyond the south (it could - just don't know for sure). I didn't interview there so take a Californian's opinion on Wake with a grain of salt!
