usuhs army vs air force

Hi- just wondering if anyone out there has an opinion about which branch is "better" (especially for docs with families) in the military- army or air force? Any opinions? I have heard from a military spouse forum that the air force is generally considered to provide a better standard of living, and that the Army is more strict about "military stuff", whatever that may mean... I have also heard that the Army deploys more often than the Air FOrce, but that if you're with the air force you are pretty much guaranteed to spend at least a couple of years stationed oversees (to which your family may accompany you...) I have also heard that you should plan to move about every 3 years or so with both branches... ANy other information out there? thanks!
