I like the fact AoPS's material is available a la carte... you can take the classes or use the textbooks alone or just use Alcumus for free... That makes it very flexible.

Also, AoPS is now an accredited school not just an enrichment center which might be a plus if you are trying to deal with public schools for advancement.
