From reading this site and others, I've found that WP vs ROTC vs OCS isn't a huge deal. What matters is the type of person you are when you go through them. There will be people of great character in ROTC and at WP just like there will be a few cadets of questionable leadership skills.
Like USMAATW said, although they might have it, the student body might not... understand what you are doing and consequently not be supportive. At WP, you are all there to be at a Service Academy, so you all have the same goal; Army.
Just my thoughts, I'm sure others have more.
