I think you should think about your reasoning for wanting to go to the individual academies. My initial inclination was towards WP. Upon further examination though, I decided on USNA. Big reasons were the location (Annapolis vs. Bear Mountain) and understanding that my choices for what I wanted to do during my time in service might change. The Army is pretty boring. Right now you will go on deployments to Afghanistan or Iraq from your crappy base in a poor Southern state. When the lengthy war deployments are over, you will spend all of your time in crappy bases in poor Southern states. Trips to Germany and South Korea will be a nice respite.
By contrast, the Navy offers a wide range of career choices and locations for you to serve. USMC, SWO, Air, NFO, Subs, Seals and EOD are the primary choices. There are a plethora of choices in the Army, but at the end of the day your job is to support the ground forces. The Navy mission varies. Just some thoughts.
